RP880A1 D4 Work/Rescue Descender
The NEW D4 work/rescue descender features a unique and innovative progressive cam action, which offers precise control at slow or fast speeds. The progressive cam works by way of one cam operating inside another cam, to provide a mechanical advantage and smoother control.
The D4 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 360°, and is made from aluminium (rather than plastic), and is coated in a specialist paint which provides extra grip. Cleverly this rotation is accompanied by audible clicks which help the user identify the correct position of the handle.
The D4 is a double-stop device with an auto-lock function which is activated whenever the operator lets go of the handle.
