ISC D4 Descender 11mm - Panic Brake

3 items left

The D4 11mm has a 240kg  Working load limit which means it is suitable for two-man rescue, without the need for the creation of extra friction.

The handle mechanism is designed to rotate through 360º making its use easier and simpler. The handle itself is made from aluminium rather than plastic and is coated in a specially chosen paint which provides extra grip. Cleverly, the handle rotation is accompanied by audible clicks which help the user identify the correct position of the handle.
