Bliss Climbing Tech - Fuse Jammer Kit
WARNING!
NOTE THAT YOUR ROPE DESHEATHS AROUND 5kN IN THE FUSE. A ROPE SOLO LEAD FALL CAN IN THEORY GENERATE 12kN DEPENDING ON THE FALL FACTOR, THE WEIGHT OF THE CLIMBER AND THE ROPE MODEL. The Fuse should therefore be used as a third hand backup device only. A knot closing the system is still mandatory. A barrel knot (double overhand) is recommended. Your primary device and its connector should be BOMBER. Read about Tom Randall’s incident on El Cap to see why.

Description
Fuse Jammer
The Best LRS Backup Device! The Fuse Jammer is a screwed + glue-on accessory to the Edelrid Fuse. It adds the function of holding the rope weight so you can feed your cache loop. Too much speed and the Edelrid Fuse will grab your rope and help activate your primary device.
Compatibility
The Edelrid Fuse is rated for ropes 10-12mm. Yann Camus has made some tests with single ropes from 8.5mm to 9.8mm and results show friction of around 1.2 to 2 kN (Sterling 9.4 brand new condition) to “full stopping power” up to desheath some ropes over 5kN with:
- Beal Opera 8.5mm (used)
- Mammut Crag 9.5mm (used)
- Edelrid Caldwell 9.6mm (used)
- Maxim Glider 9.9mm (used)
It is recommended that you test with your rope (with a full backup) and report to us so we can share your results here with the public.
Safety Notice:
Important: Edelrid does NOT support this use for the device. Attempting to use this devices for LRS can be dangerous. The Fuse Jammer cam is NOT a safety item: it is just meant to support the rope weight up to around 10 kg. The Edelrid Fuse with the Jammer does not enhance their safety for solo climbing. Proper training is crucial – learn LRS from experienced professionals, always use a backup, and never rely on a single device for your safety.
Features:
- Durable and strong for reliable use
- Optimized for Lead Rope Solo climbing
- Doesn’t interfere with normal belaying or rappelling
- Reversible modification – can be removed to restore the Fuse Except if the green cam is worn
Check out our instructional videos below for setup guidance. Don’t risk learning LRS through trial and error—get proper training! For expert advice, explore Bliss Climbing’s online courses [here]. Edelrid Fuse sold separately!
Specifications
Specifications:
- Materials: Cam and connector are alluminum. Hook and side plate are 3D-printed in lightweight yet durable PETG.
- Weight: 40 grams
- Connector Strength: 22 kN MBS
Rigorous Testing of the PETG:
- Temperature Range: Tested for durability in temperatures from -20°C (-4°F) to 40°C (105°F).
- Heat Endurance: Withstood 2 hours at 85°C (185°F) to simulate extreme heat, such as in a hot car, with no damage (although we recommend not leaving gear in such conditions).
- UV Resistance: PETG construction provides strong resistance to UV, ensuring years of consistent performance.

Aquaseal+FD Adhesive Instructions
Aquaseal+FD is a moisture-curing adhesive. For optimal results when using it with the GG Modifier, allow a 24-hour curing time.
To keep the unused portion from hardening in the tube, follow these steps:
- Eliminate Air Pockets: Squeeze Aquaseal to the tube opening to remove any air pockets.
- Seal the Threads: Apply a small amount of Vaseline on the threads before screwing on the cap. This creates an additional barrier against moisture.
- Store Properly: Place the sealed tube in a zip-lock bag and store it in the freezer.
When You’re Ready to Reuse Aquaseal: Simply let the tube warm to room temperature, or submerge it (still in the zip-lock bag) in warm water. It’s now ready for easy application!
Verified ownerSimple to install and easy to use, I feel very secure relying on the system.
Verified ownerInstallation was easy, and the Fuse Jammer works perfectly as a LRS backup device. It's nice to have a simpler solution than clove hitch cache loops for the backup.
Verified ownerSimplified my setup and worked perfectly. Easy to install. Just took it for a spin on the first pitch of The Nose!
Verified ownerThe best backup solution I’ve used so far for continuous cache loop systems! Friction is minimal, and the Fuse jammer kit makes the overall system so compact and simple. Setup time is almost nothing, and it makes me feel very safe no matter what primary device I use.
Verified ownerI have been using the Fuse jammer kit for the last few weeks starting with single pitch climbing and then a few multi-pitch climbs. I have been very impressed on how well the fuse jammer has been working. So very much better than using back up knots. I am impressed on how fast I am able to manage the cache loops which has allowed me to climber harder routes with decreased stress. So far the fuse jammer has been very durable and consistent.
