The D4 Rescue Descender is ideal for rescue, belay, descending, rope access and industrial situations. It features a unique and innovative progressive cam action for precise control at slow or fast speeds.

The double stop device has an auto-lock function which activates on handle release. The handle rotates through 360 degrees with audible clicks to help identify the correct handle position.

The descender's 240 kg working load limit allows for 2-man rescue without the need for additional friction control.
