D2 Escape Descender


The engineers at ISC developed the D2 handle operated cam descender so that in a panic/emergency situation the Descender will actually stop the descent, rather than just slow it down. The D2 can be controlled by pushing in the cam (ideally using the thumb) which allows the user to smoothly feed the rope through the device, without the use of the handle. The cam feed feature is particularly useful for fast Bail-out or for work positioning during roof work for example.

It is also easy to back-feed the rope through the D2 so it can be used for smooth ascending or for emergency hauling (when used as part of a 2:1 ‘Z-rig’). The Descender is compact and lightweight, allowing it to be carried on the harness at all times.
