Three placement modes�active cam and two passive chocks�make the Tri-Cam Evo even more versatile than standard Tri-Cams. Top of the head is wider to create an extra taper that lends additional stability to cammed placements. Stiff sling allows for easier one-handed placement and extraction. * Ideal for use in horizontal cracks, pockets, and shallow vertical cracks; can also be placed in icy cracks where regular cams won�t work.
