The all-around workhorse of the Metolius line, Power Cams are at home on any type of rock, from the big walls of Squamish granite to the desert towers of Utah Sandstone, from mountainous Rockies limestone to super-hard Gunks quartzite. Theyre also perfect whether youre free or aid climbing, high in the mountains or at a roadside crag. With the new Range Finder feature giving you instant placement feedback, they are easier and safer to place than ever Extensive testing in real rock has convinced Metolius to design Power Cams to maximize holding power. They achieve greater holding power by reducing the cam angle slightly so the cam lobes push out harder against the walls of the placement. Theyve also widened the faces of the cam lobes to get more grip and to spread the force of a fall over a larger area.
