Grivel A & D is a classic ascender, that through the introduction of the plate on the body can also be used for rappelling. This solves one of the problems that often arise in the use of ascenders, which have always been designed and functional to climb up, but which become difficult to unlock and which do not allow the double phase.

It is enough to insert the rope under the cam into the plate, insert a carabiner, unload the weight for a moment to open the cam, and start the descent as with a normal plate.
Used, also in expeditions, to go up on fixed ropes, it can also become the descent system on these same ropes.

The large ring at the bottom allows it to be connected with the harness. Ergonomic and spacious handle easy to use even with gloves. Practical ring on the cam to facilitate the manipulation and help unlocking.
