ISC D4PRO Work/Rescue Descender (no Panic Brake)

ISC’s D4PRO Descender has been designed based on valuable insights from seasoned Rope Access & Rescue professionals.

Built upon the acclaimed D4TM Work/Rescue Descender (RP880), the D4PRO offers the same reliability and performance but with a notable difference – it does not feature a panic-brake function.

This omission responds directly to feedback from experienced users who seek a device tailored for specific applications such as longer descents and rescue/belay scenarios, where a broader ‘sweet spot’ is preferred.

Certified to EN 12841 standards, the D4PRO ensures compliance without the inclusion of a panic brake. It’s the ideal choice for those seeking enhanced control and flexibility in their descent operations.

For those requiring adherence to ANSI standards, our RP880 D4 Work/Rescue Descender is equipped with a panic-brake function to meet those requirements.
