D2 Escape Descender - ISC

ISC Wales


Notify me when this product is available:

The engineers at ISC developed a new handle operated cam system specifically so that in a panic situation the Descender would actually stop the descent, (rather than just slow it down). The D2 Descender is the only MicroDescender in the world to offer this function.

Collections: Escape/Bailout, Hardware, ISC Wales

Category: Escape, NFPA 1983 E

Type: Hardware

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 in Bail-out Operations.

It is also easy to back-feed the rope through the D2 and therefore it can be used for smooth ascending or for emergency hauling, (when used as part of a 3:1 ‘Z-rig’).

The Descender is compact and lightweight, allowing it to be carried on the harness at all times - some harness manufacturers have integrated it into a harness back-pack so that self-rescue can be made easy.
