Our new Ultrascenders are designed to be the most convenient and
easy to use ascenders around. We've added a new
ergonomically designed safety mechanism which is integrated into the
handle channel for maximum ease of use in those long "over the lip"
stretches. There's a new thumb notch in the cam top to simplify full cam
retraction, and a new molded handgrip for maximum comfort on those
long pulls. The cams in CMI Ultrascenders are 4140 chrome-moly steel.
This high strength material allows us to impart a new, patented,
non-metallic finish to the cams. The new finish gives the cams the
same corrosion resistance as stainless steel yet increases both the
tensile and yield strength. Additionally, the new finish is harder
than the best knife blades or files which allows us to
cams against wear out for life! Team these new features with our
extruded and machined bodies, stainless steel springs and operating
parts, and you've got the best ascender available!
