Controled descent

For both work at height and rescue, access from above is preferable because it allows one to take advantage of the force of gravity. Descenders are designed to regulate friction and control the descent on a fixed rope. They allow a worker to position himself at any point on the rope. Some descenders such as the Petzl I'd can also be used to safely belay a leader using rock climbing techniques.

Ease of use

Self-braking descenders provide ease of use and increased safety when moving on a single rope. The braking mechanism consists of a pivoting cam which pinches the rope and brakes the descent when the handle is released. New for 2009 The new versions of the I'D S and I'D L descenders have a new handle which allows easier movement over horizontal or low-angle terrain.

I'D S D20OSO Self-braking descender with anti-panic function for working on fixed ropes

Designed for work on a rope: the gate on the swinging side plate helps prevent dropping the device
Multi-functional handle allows the user to:
- unblock the rope and control the descent with the hand on the braking side of the rope
- move more easily on horizontal or low-angle terrain thanks to the button on the handle
- to position himself while on the rope
Anti-panic function is engaged if the user pulls too hard on the handle: the pivoting cam is released and automatically brakes to stop the descent
Anti-error safety cam to reduce the risk of an accident due to incorrect installation of the device on the rope. The shape of the cam is designed to improve rope glide during an ascent.
Pivoting cam makes it easier to take up the slack in the rope Can also be used to make a reversible haul system, and for short ascents (in conjunction with a FOOTPRO footloop and an ASCENSION handled rope clamp).
