ISC D4 PRO Descender

 ISC D4 PRO Work/Rescue Descender (10.5-11.5mm Rope)

The standard D4™ Work/Rescue Descender (RP880) has proven to be a popular Descender amongst Rope Access & Rescue users, all over the world.  Many users value the extra peace of mind of having a panic-brake function.

Feedback gathered from highly qualified and experienced 'Pro' users highlighted a demand for a device which does not incorporate a panic-brake function.  Enter the D4PRO!  The D4PRO Descender is the same great Work/Rescue Descender, but without the panic brake. 

This can be particularly useful on longer descents and in rescue/belay applications, where a broader 'sweet spot' is welcomed.

As the D4PRO does not incorporate a panic-brake, it is not possible for the device to fully meet the criteria of NFPA and ANSI Standards.  The D4PRO is fully certified to EN 12841 (a panic brake is not a compulsory criteria of this standard).
 
If you require a Descender which fully meets NFPA/ANSI standards, please see RP880 D4 Work/Rescue Descender, (with incorporated panic-brake).
