Description
The NEW D4 Work/Rescue Descender features a unique and innovative cam
action, which offers precise control at slow or fast speeds. The progressive cam
works by way of one cam operating inside another cam.
The D4 has a 240kg (500lbs) 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.
