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).
