Petzl I’D Descender.

For descending a rope and for belaying, with an anti-panic function. Swinging side plate with safety catch: decreases risk of dropping device, allows rapid installation of the rope into the device, increases efficiency when passing intermediate anchor points. Increased safety: anti-error feature to help avoid accidents due to incorrect installation of the rope in the device. Self-braking system: if the handle is released during descent, the cam rotates to pinch the rope and brake the user's descent, anti-panic handle: the I'D® will lock onto the rope if the user pulls too hard on the handle. Comfortable to use: to descend, simply pull on the handle; the rate of descent is controlled by varying the grip on the free end of the rope with the other hand, for work positioning, the handle can be rotated to secure the I'D® in place on the rope, thus eliminating the need to "tie off" the device. Ascending the rope is possible without changing the position of the device: simply add a footloop and a handled rope clamp / grab. May be used to belay a leader or a second.May be used as a progress capture device in a haul system; allows rapid conversion between raising and lowering. For rope diameters from 11.5 to13 mm.
