Our ascenders have been there on first ascents, grueling expeditions, and daring rescues, always returning to climb another day. CMI Ascenders are chosen by the most demanding users.
- Bodies. Our ascender bodies are extruded from aircraft grade aluminum and stainless steel. The aluminum bodies are finished with a hard powder coat to permanently protect them from the elements. All of our ascenders easily accomodate 5/8" ropes. Numerous tie-in points accomodate the largest carabiners in use today.
- Springs. The 17-4PH stainless steel springs in our ascenders are tested to over a million cycles, simulating lifetimes of the most demanding use.
- Cams. Newly redesigned with a more aggressive grip and a thumb notch to simplify retraction. Cast from 4140 chrome-moly steel and finished with an exclusive non-metallic finish to to give the cams the same corrosion resistance as stainless steel. We guarantee our cams for life--if you can wear one out, we'll replace it--free!
- Handgrips. Our molded plastic handgrips fit the contour of the ascender and feature an integrated safety that is easier to use and more comfortable on the hand than any other ascender on the market.
