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 [here]. 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
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].

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!

A very effective device for hanging your protection equipment off your neck with a sling or chest. Rig does no damage to the device at all. No drilling needed perfect complement for a device and such use and it looks good too.


I had already modified my Grigri 3 and Grigri plus in the past. However, in my opinion no improvised solution is better than a BCT modifier. It's position is ideal for the optimal feed, it is ergonomic and it looks awesome! I would definitely suggest it to everyone!

The GG Modifier comes with clear instructions, which makes it very easy to install. This means you can modify your grigri to hold it upright for lead rope soloing, without drilling holes in it. If desired, the modifier can be removed without altering the grigri’s integrity. I tested it once and I’m very happy with it.


The GG Modifier Kit is fantastic, it has taken all the hassle away.
It fits absolutely perfectly and once I applied the glue I was able to position it in exactly the right place before leaving it to dry.
Clearly time and thought has gone into creating this and I would certainly recommend getting one.
Thanks ⭐️⭐️⭐️⭐️⭐️
