Petzl I'D descender 11.5-13mm "G" Designed for rescue: lacks gated attachment hole. Multi-functional handle allows the user to : - unblock the rope and control the descent with the hand on the free end of the rope - move more easily on horizontal or low -angle terrain, thanks to the button on the handle - get into position without having to tie off the device Anti-panic function is engaged if the user pulls too strongly on the handle: brakes and stops the descent automatically. Anti-error safety catch 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 when ascending. 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 FOOTPRO foot loop and an ASCENSION handled rope clamp).
