Rope climbing is made easier by the CMI Foot Ascender. The addition of this boot-mounted device maintains tension on the rope, allowing for easier advancement of the main ascender, and promotes better use of body mechanics by keeping your body in an upright position. The body is crafted from anodized aluminum, and the hardcoated cams carry our exclusive wear-out guarantee. If the cam EVER wears out, we will replace it at no charge. Available in left and right foot models. Weight 11.2 oz. (320 g). Made in the U.S.A.
