Descenders

The ISC D4 Work/Rescue Descender is a double-stop device with an auto-lock function and a panic brake which is not overly sensitive in normal use. The cam is made with a super hard solid stainless steel and is highly wear and corrosion resistant. The D4 is compliant with CE Standards, NFPA T and ANSI Z359.4 for the worldwide Rope Access and Rescue markets which typically use 10.5mm/11mm ropes.

The ISC Rescue Figure 8 features extended side bars designed to keep your rope securely in place, preventing it from slipping inward and causing accidental locking.
