The Metolius Master Cam combines a nice, flexible cable with an ultra narrow head for hard aid or free climbing. Since metolius invented the CNC milled cam stop, they naturally applied them to Master Cams. The longer body affords additional reach when top stepping or stretching for that hard to get placement. The Range Finder system also provides critical placement feedback for those who need it. Master Cams are hand built in Bend, Oregon. Each one is thoroughly inspected and every unit is tested to 5 kN or above. Master Cams are CE and UIAA certified.
