These award winning Ultralight Power Cams utilize Direct Axle Technology™ to remove every unneeded scrap of material to make them as lightweight as possible, while maintaining the ultra-strong construction that Metolius is known for. These 4-cam's narrow head profile allows them to fit into smaller pockets than previous models, and the range finder (sizes 2-8) tells you how good your placement is. Spectra slings lighten these cams even further.
