Petzl I'D

The Petzl I’D’s are self-braking descenders with anti-panic functions. There are two variants the Petzl I’D S (small) which is for roped access operations using 10.0 to 11.5 mm diameter ropes and the I’D L (large) which is designed for rescue applications using thicker 12.5mm - 13.0mm ropes.

The Petzl I'D S has long been the default self-locking descender for tactical operations involving abseiling or rappelling as it allowed operators to instantly to stop or start a descent with needing to lock-off/un-lock the rope. It also allows transitioning into ascent easily if a position is overshot – the rope can be pulled through the device without needing to release the handle. The descender allows operators to move both horizontally and vertically whilst being able to position themselves without tying off the device or physically moving the handle to a “safe” position.

Both the I'D S and I’D L include an anti-panic function that stops the descent if the handle is pulled too far and an anti-error safety catch that reduces the risk of an accident if the device is rigged incorrectly.

There is a safety clip on the swinging side plate that reduces the risk of dropping the device when removed from rope, such as when passing intermediate anchors. The latest models also allow the rope to be inserted whilst the I’D is still connected to the harness

The I’D S can be used with rescue loads up to 250kg and 150kg for single operators whilst the I’D L can be used for rescue loads up to 280kg.

The I’D’s allows the rope to be either run over the side of the device onto a chunky stainless steel wear plate or if you want more friction through a V-channel in the front of the device. The I’Ds can also be fitted with an optional open or closed friction brake that bolts onto the side of the body – this allows additional friction to be created when handling heavy loads.

I'D S is certified for use on a wide range of ropes:
