Description
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 is a double-stop device with an auto-lock function which is activated whenever the operator lets go of the handle.
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. The D4 is the only ANSI certified descender on the market today.
