ISC D4PRO Descender

The standard D4 Work/Rescue Descender 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 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 this device to fully meet the criteria of NFPA or 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 the D4 Work/Rescue Descender, (with incorporated panic-brake).
