Grivel A & D Ascender Descender
The revolutionary A & D Ascender can also be used as a descender, adding serious convenience to your big wall adventure. 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. Used 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. The ergonomic and spacious handle is easy to use even with gloves, while the practical ring on the cam helps facilitate manipulation and unlocking.
