ISC D4 Work Rescue Descender Double stop anti panic-ANSI RATED-10.5-11.5mm (7/16")fit

The 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 aluminum 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.
