Bliss Climbing Tech - GG Modifier Kit (With Glue)
WARNING!
Some videos on LRS might give the impression that Grigris are reliable enough to catch inverted falls (especially the Grigri+) in a held-upright setup. But remember, those videos also strongly recommend using backups. The Grigri+ (and other models) can perform inconsistently in certain scenarios, including but not limited to inverted falls, and without a backup, there’s a significant risk. Recently, too many climbers have faced close calls. For your safety, always include a reliable backup method in any LRS setup—it’s essential. Like Andy Kirkpatrick wrote “The backup is the belay”.
Watch these two videos to see for yourself:

Description
GG Modifier for Lead Rope Solo (LRS) with a GriGri
No more drilling needed! The GG Modifier is a glue-on accessory that secures your GriGri in the held-upright position, designed specifically for Lead Rope Solo climbing. By adding a secondary attachment point with a breaking strength of 40-60 kg, this modification offers an ideal angle for solo climbing with a GriGri.
Compatible Devices:
- Petzl GriGri+
- GriGri (2019 version)
- GriGri 2
- NEOX
This accessory allows you to use your GriGri for Lead Rope Solo (LRS) climbing without altering the device permanently. It’s also removable, so you can return your GriGri to its original state anytime.
Safety Notice:
Important: Petzl officially prohibits using the GriGri and NEOX for Lead Rope Solo. Attempting to use these devices for LRS can be dangerous. The GG Modifier 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
- No drilling required—preserves the GriGri’s integrity
- Optimized angle for Lead Rope Solo climbing
- Doesn’t interfere with normal belaying or rappelling
- Field-serviceable—the string is easily replaceable if needed
- Reversible modification—can be removed to restore the GriGri

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 ownerGreat innovation that allows you to use your Grigri for those solo outings, while keeping the device safely untouched, so you still feel very safe belaying people. No need to damage your device anymore!
Verified ownerThe GG Modifier is great for those who don’t want to drill and potentially mess up their GG but want to use their GG in the held upright position for LRSing. It eliminates the question of where and how to drill the Grigri; it is stronger than drilling the plastic spine; and eliminates the frustration of threading a cord through the interior of the GG. I found the Grigri Modifier is easy to put on if instructions are followed (and removed if desired). It is lightweight and the chest harness attachment point is optimized for most rope-Grigri combos. I don’t know how long the removable glue will last, but two part epoxy can always be used to attach it permanently. PS - it will not catch head first falls - use backups!
Verified ownerThe GG Modifier is very nice and easy to install. Best of all it takes the guess work out of where to drill your grigri or removes the ugly string if you decided to hang the grigri with a string tied to the front and back.
The GG Modifier does not interfere with normal use of the grigri.
