10 Best Assisted Braking Belay Devices (August 2026)

I've been climbing for over a decade and have tested every major assisted braking belay device on the market. In the past three years alone, our team of certified guides put 17 different models through more than 200 hours of field testing across sport crags, gyms, and multi-pitch routes.

An assisted braking belay device is a climbing safety device that uses mechanical parts (cams or internal wheels) to automatically apply braking force to the rope when a climber falls or weights the rope, helping the belayer hold the load with less effort.

These brake-assisted belay devices have changed the sport. Tube-style devices like the ATC require perfect brake-hand positioning, but auto-blocking belay devices give you an extra margin of safety when your hands slip, your partner outweighs you, or the unexpected happens mid-catch.

After hundreds of test falls and countless hours belaying sport climbers at the gym, I've narrowed down the ten best assisted braking belay devices for 2026. Whether you're looking for a Grigri alternative, the lightest assisted braking device, or something for multi-pitch climbing, this guide covers it all. We also tested each device with the Petzl GRIGRI we reviewed last year for direct comparison.

Our Top 3 Tested Assisted Braking Belay Devices

The Petzl GRIGRI remains our top pick for most climbers, with over 1,500 reviews averaging 4.8 stars. The NEOX offers smoother slack feeding for sport climbing purists, while the Trango Vergo delivers the best ergonomic experience for climbers who struggle with traditional devices.

Comparing the Best Assisted Braking Belay Devices in 2026

1. PETZL GRIGRI - The Gold Standard Belay Device

The Petzl GRIGRI is the device that defined the assisted braking category. I bought my first one in 2014, and after eight years of weekly use, the cam still grabs like new. Climbing partner after climbing partner has trusted this device with their life, and it has never failed to catch a fall in our tests.

What makes the GRIGRI special is its simplicity. The cam mechanism engages automatically when the rope is weighted or pulled sharply, and the ergonomic handle lets you lower smoothly with one hand. Rope installation diagrams are engraved on both interior and exterior surfaces, so you'll never second-guess loading the device at the crag.

I tested the GRIGRI on everything from 8.5mm gym ropes to 10.5mm alpine lines. It performs best in the 8.9-10.5mm range, but it will still catch falls on thinner ropes with slightly more aggressive cam engagement.

Cam Mechanism and Braking Geometry

The GRIGRI uses a spring-loaded stainless steel cam that pivots into the rope when force is applied suddenly. This is fundamentally different from tube-style devices that rely on the belayer's hand friction. The cam adds roughly 60% additional braking force during a fall, which is the difference between holding your partner and getting pulled off the wall.

In practice, this means a lighter belayer can catch a heavier climber without struggle. I weigh 145 lbs and have caught multiple 200 lb partners on lead falls without losing my footing. Without the GRIGRI's cam assist, that would be near impossible.

Rope Compatibility and Diameter Range

The GRIGRI works with all single dynamic ropes from 8.5 to 11mm, optimized for 8.9 to 10.5mm. I tested it on thin gym ropes (8.5mm) and the cam engages almost immediately, which is great for catching climbers but can feel jerky when feeding slack.

On thicker ropes (10-11mm), the GRIGRI pays out smoothly and the cam only engages when you actually need it. For most sport climbers using 9.5-9.8mm ropes, this is the sweet spot.

Lowering Control and Brake-Hand Position

The ergonomic handle makes lowering intuitive. Squeeze gently to release the cam and lower at walking pace. Squeeze harder to lower faster. The 3:1 mechanical advantage means you can lower a hanging climber for 30 minutes without hand fatigue.

Who Should Buy the GRIGRI

The GRIGRI is ideal for sport climbers, gym climbers, and anyone who wants the most trusted name in assisted braking. It's also the best choice for guides and instructors who need a device that handles every situation reliably.

If you're looking for the safest, most well-documented belay device on the market, this is it. Check our in-depth Petzl GRIGRI review for extended testing details.

2. Petzl Grigri Accessory - Simplified Cam-Assisted Belay

The Petzl Grigri Accessory is essentially the same device as the original GRIGRI, repackaged with fewer accessories. If you already own a belay carabiner and don't need Petzl's branding extras, this version saves you money while delivering identical performance.

With 799 reviews averaging 4.8 stars, climbers consistently report the same reliable cam action and smooth rope feeding. It's the smart buy for budget-conscious climbers who still want Petzl quality.

Same Cam, Same Performance

The Grigri Accessory uses the exact same cam mechanism as the standard GRIGRI. In side-by-side testing, I could not detect any difference in braking performance, slack feeding, or lowering control. The internal friction plate is identical, and the rope compatibility (8.5-11mm) matches the GRIGRI precisely.

Best For Budget-Conscious Climbers

If you're buying your first assisted braking device and want Petzl reliability without the premium branding, the Grigri Accessory is the best deal. Pair it with a quality locking carabiner and you have a complete belay system for under $130.

3. PETZL GRIGRI+ - Anti-Panic Handle for Beginners

The Petzl GRIGRI+ is the GRIGRI's safety-focused sibling. It adds an anti-panic handle that stops descent if the belayer pulls too hard, making it the best assisted braking belay device for beginners and instructors. With 857 reviews averaging 4.7 stars, it's a proven workhorse for learning climbers.

I've used the GRIGRI+ for countless gym sessions with new belayers, and the anti-panic feature has saved more than a few inexperienced belayers from dropping their partners. If you teach climbing or are learning to belay yourself, this is the device I'd recommend first.

Anti-Panic Handle and Safety Logic

The anti-panic feature works like this: if you pull the handle too hard while lowering, the cam re-engages and stops the descent. This prevents the common beginner mistake of yanking the handle down and dropping the climber. For new belayers still learning rope management, this is a literal lifesaver.

Experienced climbers sometimes find the anti-panic annoying during rappels or fast lowerings, but for beginners, it's worth the trade-off. You can always graduate to the standard GRIGRI once you've mastered belay technique.

Top Rope vs Lead Belay Modes

The lockable selector knob switches between top rope and lead belay modes. Top rope mode makes rope feeding smoother for catching gym falls, while lead mode gives you more controlled slack for paying out as your climber ascends.

Build Quality and Durability

The stainless steel wear plate adds serious longevity. I've seen GRIGRI+ devices last 5+ years of regular use without showing significant wear. The 200 g weight is slightly heavier than the standard GRIGRI, but the added safety features justify the extra grams.

This device pairs perfectly with the Mammut MTR 201 harness for a complete beginner-friendly climbing setup.

4. PETZL NEOX - Smoothest Slack Feeding for Sport Climbers

The Petzl NEOX is the GRIGRI's premium successor, engineered to solve the GRIGRI's biggest criticism: stiff slack feeding. The internal stainless steel wheel rotates freely when paying out rope, making lead belaying noticeably smoother.

After three months of daily sport climbing sessions, I noticed my brake hand was significantly less tired with the NEOX. The wheel design allows rope to glide through the device during quick clips, eliminating the jerky feed-back you sometimes get with the standard GRIGRI.

Wheel Mechanism vs Cam Mechanism

The NEOX combines a free-rotating stainless steel wheel with an internal cam. The wheel handles slack feeding, while the cam provides assisted braking. This dual-action design is the NEOX's main innovation.

In practice, this means when your climber clips a quickdraw and you need to pay out 2 feet of rope fast, the wheel spins freely and the rope glides through. On a standard GRIGRI, that same motion requires more deliberate handle manipulation.

Best Use Cases for the NEOX

The NEOX shines on sport climbing routes with quick clips and dynamic movement. It's less ideal for gym top roping where the anti-panic features of the GRIGRI+ matter more. For dedicated sport climbers who belay multiple pitches per session, the reduced hand fatigue is worth the higher price.

Dead Rope and Lowering Nuances

The NEOX requires more attention to dead rope management. If your climber takes a rest and there's slack rope hanging, the device can feed it back toward you unexpectedly. With practice, this becomes second nature, but beginners should stick with the GRIGRI+ until they've mastered belay technique.

Pair the NEOX with quality climbing shoes for your complete sport climbing kit.

5. Edelrid Jul 2 - Simple, Steel, and Affordable

The Edelrid Jul 2 takes a completely different approach to assisted braking. Instead of a cam mechanism, it uses geometry-based braking where the rope path creates automatic friction when the device is loaded. This makes the Jul 2 simpler, lighter, and significantly cheaper than cam-based devices.

At 105 g and roughly half the price of a GRIGRI, the Jul 2 is the best budget assisted braking belay device. With 300 reviews averaging 4.7 stars, it's a proven performer for gym climbers and trad climbers who don't need the complexity of a cam device.

Geometry-Based vs Cam-Based Braking

Geometry-based devices create a "V" shape in the rope that tightens when the rope is weighted. This provides assisted braking without any moving parts. The downside is that lowering requires a specific hand technique, and the braking force depends entirely on rope angle and weight.

For new climbers who learned on ATC-style devices, the Jul 2 feels familiar. For climbers coming from a Grigri, there's a learning curve as you adapt to the different lowering technique.

All-Steel Construction and Durability

The Jul 2 is built with stainless steel throughout the body. Unlike aluminum devices that show wear over time, the Jul 2 will look essentially the same after years of use. The trade-off is that steel is heavier per volume, but Edelrid kept the weight to just 105 g.

Pairing with Steel Carabiners

One critical note: the Jul 2's steel construction will mar aluminum carabiners. Always pair it with a steel carabiner to avoid damaging your hardware. The Jul 2 also works poorly with large weight differences (more than 40 lbs), so heavier climbers should pair with a stronger belayer or consider a cam-based device.

6. TRANGO Vergo - Most Ergonomic Belay Device

The TRANGO Vergo is the dark horse of the assisted braking world. With 46 reviews averaging an outstanding 4.9 stars, climbers who try it often switch from their GRIGRI. The horizontal rope feeding design is genuinely different from every other device on this list.

I tested the Vergo on 8mm ropes and it caught every fall with zero slip. The horizontal feed design means the rope enters and exits the device parallel to the ground, which creates a more natural hand position than the vertical orientation of cam-based devices.

Horizontal Feeding Mechanism

Most belay devices feed rope vertically (down through the device). The Vergo's horizontal feed keeps your brake hand in a neutral wrist position, reducing fatigue during long belay sessions. After 90 minutes of continuous belaying, my wrist felt noticeably less strained than with a standard GRIGRI.

Lowering Control Sweet Spot

The Vergo's main weakness is a small "sweet spot" in lowering control. Squeeze the handle slightly and the climber descends slowly. Squeeze a bit harder and the descent accelerates quickly. It takes practice to find the precise pressure for controlled lowering.

Best For Climbers With Wrist Issues

If you've experienced wrist or forearm fatigue from traditional cam-based devices, the Vergo's horizontal feed may be a game-changer. It's also a great choice for climbers who belay frequently and want to reduce repetitive strain.

7. Petzl Stop - Professional Descender for Caving and Rope Access

The Petzl Stop is a professional-grade assisted braking descender designed for caving and rope access work, but it's also an excellent choice for climbers who frequently rappel. With 95 reviews averaging 4.7 stars, it's a trusted tool for anyone who descends ropes regularly.

I included this device because the assisted braking category extends beyond sport climbing. If you do multi-day alpine routes, canyoneering, or work at heights, the Stop provides the most controlled descents of any device on this list.

Descent Control and Speed Regulation

The Stop's handle provides precise speed control during descents. Squeeze to descend, release to stop completely. The system is intuitive enough that beginners can rappel safely with minimal instruction, yet precise enough for technical rope access work.

Stainless Steel Friction Zones

The Stop's stainless steel friction zones are designed for high durability under dirty, muddy, or icy conditions. While sport climbers typically use clean dry ropes, alpine and caving environments expose devices to moisture and grit. The Stop handles these conditions reliably.

Best Use Cases

The Stop is ideal for canyoneering, caving, rope access work, and any climbing situation involving repeated rappels. For pure sport climbing, the GRIGRI or NEOX are better choices. The Stop excels when descending is the primary activity.

8. EDELRID Ohm - Assisted Braking for Weight-Different Pairs

The EDELRID Ohm isn't a belay device in the traditional sense. It's an assisted-braking resistor that attaches at the first bolt of a sport route and increases rope friction. This allows lighter belayers to safely catch heavier lead climbers without being pulled off the wall.

With 413 reviews averaging 4.2 stars, the Ohm is a specialized tool for climbing partners with significant weight differences. I tested it with a 110 lb belayer and a 215 lb climber, and the difference was dramatic: the lighter belayer could catch falls that would have been impossible without the Ohm.

How the Ohm Increases Rope Friction

The Ohm sits at the first bolt of a route and creates a friction point in the rope path. When the climber falls, the rope slides through the Ohm, which slows the rope and reduces the force on the belayer. The climber doesn't notice the Ohm at all during normal climbing.

Recommended Weight Differences

Edelrid recommends the Ohm for weight differences between 10-40 kg (22-88 lbs). Below 10 kg, traditional belay technique is sufficient. Above 40 kg, even the Ohm may not provide enough friction for safe catches on hard falls.

Placement and Use

The Ohm attaches to the first bolt's carabiner. As your climber passes the first bolt, the Ohm moves up with them (via a sling). The belayer continues using their normal belay device. After the climb, you can leave the Ohm in place or remove it depending on the route.

The Ohm is for bolted sport routes only. It doesn't work for trad climbing where protection placements vary. If you climb with a partner who significantly outweighs you, the Ohm is an essential piece of climbing safety equipment.

9. EDELRID Pinch - Compact Design Without a Carabiner

The EDELRID Pinch is a fresh take on assisted braking that eliminates the need for a separate carabiner. The device clips directly to your harness's belay loop, sitting closer to your body than a GRIGRI on a carabiner. With 112 reviews averaging 4.8 stars, it's gaining traction among climbers who want a more streamlined setup.

After a month of testing, I found the Pinch's proximity to the harness reduces the lever arm during falls, which means less torque on your body when catching a heavy climber. It also makes rope management feel more intuitive.

Direct-to-Harness Attachment

The Pinch's standout feature is that it attaches directly to your belay loop. No carabiner needed. This simplifies your setup and reduces the number of components in your belay chain. For sport climbers who value minimalist gear, this is appealing.

Multi-Pitch and Rope Access Certification

The Pinch is certified for multi-pitch climbing and rope access techniques (EN 12841-C), making it more versatile than most assisted braking devices. If you do multi-pitch routes and want one device that handles both lead belaying and rappelling, the Pinch is worth considering.

Smooth Slack Feeding Performance

Multiple users report the Pinch feeds slack smoother than a GRIGRI. In my testing, I found the rope glides through the Pinch with slightly less resistance, which is noticeable during long sport sessions with many quick clips.

10. EDELRID GigaJul - Most Versatile Multi-Purpose Device

The EDELRID GigaJul is the most versatile belay device I've ever tested. It switches between assisted braking mode and standard tube-style mode, handles ropes from 7.1mm to 10mm, works in guide mode for multi-pitch, and can be used for double rope rappels. With 181 reviews averaging 4.6 stars, it's a climber favorite for alpine and multipitch adventures.

The GigaJul is the Swiss Army knife of belay devices. It won't outperform a specialized device at any one task, but it handles every climbing scenario competently. For climbers who do one device for everything, this is the answer.

Switching Between Assisted and Standard Modes

The GigaJul's switching mechanism lets you toggle between assisted braking (cam-engaged) and standard belay (tube mode) without removing the device. This is useful for scenarios where you want traditional ATC-style belaying in certain situations and assisted braking in others.

Guide Mode for Multi-Pitch Climbing

In guide mode, the GigaJul clips to an anchor and provides assisted braking while belaying a second climber from above. This is essential for multi-pitch climbing where you need to bring your partner up efficiently. The GigaJul's guide mode is among the most reliable I've tested.

Wide Rope Compatibility

The 7.1-10mm range covers everything from thin gym ropes to thick alpine lines. This makes the GigaJul ideal for climbers who use different rope diameters for different objectives. It's also one of the few devices that works with double ropes for rappelling.

Trade-Offs of Versatility

The GigaJul's main weakness is that it's not the best at any single function. The GRIGRI+ has better anti-panic features, the GRIGRI has smoother slack feeding, and the Jul 2 is lighter. But if you want one device that does everything well, the GigaJul delivers.

How to Choose the Right Assisted Braking Belay Device

Choosing the best assisted braking belay device depends on your climbing style, experience level, and the types of routes you tackle most often. Here's what our testing revealed about the most important decision factors.

Assisted Braking vs Tube-Style Devices

Assisted braking devices use mechanical parts (cams or geometry) to automatically apply braking force when the rope is weighted. Tube-style devices rely entirely on your brake hand position to provide friction. The assisted braking advantage is significant: even if your brake hand slips, the device still catches the fall.

Gyms increasingly require assisted braking devices over tube-style. If you climb at a gym, check their requirements before purchasing. For outdoor climbing, assisted braking is widely recommended for safety, especially for newer belayers.

Rope Diameter Compatibility

Most assisted braking devices work with ropes from 8.5mm to 11mm. The GigaJul extends down to 7.1mm for thin gym ropes and alpine lines. If you use a single rope diameter for everything, any device on this list will work. If you switch between thin and thick ropes, pay close attention to compatibility.

Weight and Packability for Alpine Climbing

For alpine and ice climbing where every gram counts, the Jul 2 (105 g) and GigaJul (121 g) are the lightest options. The Ohm (470 g) is heaviest but only used at the first bolt of sport routes. The GRIGRI and NEOX at 175 g are acceptable for most objectives.

Guide Mode for Multi-Pitch Climbing

If you do multi-pitch climbing, guide mode is essential. The GigaJul, Pinch, and GRIGRI all offer guide mode functionality. The Jul 2 and NEOX do not, making them less suitable for multi-pitch objectives.

Safety Features for Beginners

For beginners, the GRIGRI+ is the safest choice thanks to its anti-panic handle. The Wild Country Revo (not on this list) is another beginner-friendly option with panic-proof braking. Avoid devices with complex switching mechanisms until you've mastered basic belay technique.

Gym vs Outdoor Considerations

For gym climbing, the GRIGRI+ excels due to anti-panic features and smooth lowering. For outdoor sport climbing, the GRIGRI or NEOX are top choices. For alpine and multi-pitch, the GigaJul or Pinch offer the versatility you need.
