CMC Ascender

Compact, Lightweight Rope Grab

The CMC Ascender is designed for use primarily as a haul grab in mechanical advantage systems but also as a personal ascender in a rope ascension system.

The device utilises a spring actuated, removable cam to facilitate either unloaded progression or loaded gripping on a tensioned or untensioned rope.

Based on an industry proven design and CNC machined from solid aircraft grade alloy for superior strength, the CMC ascender also features:
  • A single removable pin system for attaching and removing the device from the host rope
  • A smooth cam (i.e. no teeth) interface with the host rope, negating the risk of rope sheath damage in an overload situation
  • A large connection hole that will accept the biggest rescue carabiners
  • Distinctive red hard coat anodizing for easy identification and long service life
  • Will accept up to 13mm (1/2”) kernmantle rope
  • Made by CMC in the USA
What we love about the CMC Ascender

It’s classic design! Need we say more ….. it’s easy to operate, even with gloves on and the large connection hole makes this a versatile go to tool in the kit bag.
