Grivel Rock Safety A&D
The Grivel Rock Safety A&D is a left or right ascender and descender with an intuitive design for simple and easy operation in all weather conditions. The Grivel Rock Safety A&D uses a thumb push plate that allows for one-handed locking and unlocking / switching between ascend and descend modes, with a built-in belay plate for instinctive rappelling.
|ROPE DIMENSIONS||[UP] 8.3 ≤ Ø ≤ 13; [DOWN] 7.3 ≤ Ø ≤ 13|
Built-in Belay / Rappel Plate
Create a bite in the belay plate, hook a carabiner onto the loop, and you have an instant rappel device.
Easy to Operate
Rope can be locked/unlocked and rappel/descend modes can be selected with the flick of a thumb; very easy to operate with gloves.
A security carabiner can be hooked through the hole at the top of the device to prevent rope slippage.
