FOR RESCUE: The I'D L is a self-braking descender designed for a technical rescue. MULTI-FUNCTIONAL HANDLE: Unlocks the rope and controls the descent with the hand on the free end of the rope; moves more easily on horizontal or inclined terrain, thanks to the button on the handle. ANTI-PANIC FUNCTION: Will activate if the user pulls too hard on the handle; it brakes and stops the descent automatically. ANTI-ERROR CATCH: Helps to reduce the risk of an accident due to incorrect installation of the device on the rope. TAKES YOUR SLACK: Pivoting cam facilitates taking up the slack in the rope; can also be used to make a reversible haul system, and for short ascents (in conjunction with a FOOTAPE or FOOTCORD foot loop and an ASCENSION handled rope clamp). Safety is paramount in the work environment, especially if your job is hanging hundreds of feet in the air - Petzl's ID Descender is a self-braking descender with an anti-panic function for working on fixed ropes, and a gate on the swinging side plate that helps prevent dropping the device. The multi-functional handle allows you to unblock the rope and control the descent with the hand on the braking side of the rope, and to move more easily on horizontal or low-angle terrain thanks to the button on the handle.
