D4PRO Work/Rescue Descender

D4PRO Work/Rescue Descender

Feedback gathered from highly qualified and experienced 'Pro' users highlighted a demand for a D4 Work/Rescue Descender 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 ANSI Standards.  The D4PRO is fully certified to EN 12841 and meets NFPA 1983 (a panic brake is not a compulsory criteria of these standards).
If you require a Descender which fully meets ANSI standards, please see
