Show Description

The Rescucender is a strong ascender-like rope clamp that is designed to minimize rope damage in the event of accidental shock-loading. It does this by virtue of a cam design that can slip when a certain load is engaged. This rope clamp fully encloses the rope, so it is not great for ascending situations where frequent on-and-off of the ascender is necessary.

  • Takes ropes 11 to 12.5mm (7/16in. to 1/2in.).
  • CE approved.
  • Individually tested.
