In February, 2005, CMI became compliant with the ISO 9001 Standard (2000 edition) for quality management systems, the most recognized standard in the industry.


CMI Ascenders have long held the reputation of being the strongest, most reliable ascenders available. The new ergonomically designed safety mechanism is integrated into the handle channel for maximum ease of use. The new thumb notch in the cam simplifies full cam retraction. The moulded handgrip on the Ultra gives maximum comfort on long hauls.

The new coating process on the cam gives increased corrosion protection, and superior wear characteristics. So good in fact that CMI gives a lifetime "Wear-out" guarantee on the cams. If you ever wear one out, we'll replace it FREE.
