ISC D4 Pro Rope Access Descender

Enter the D4PRO! 

The D4PRO Descender is the same great Work/Rescue Descender, butwithout 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 D4PROis 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).
