When outfitting our cams with 'biners, we do it with the Metolius F. S. Mini II Jet Carabiner Set. Each 'biner is a different color to match our cams, while the compact size minimizes weight without sacrificing strength. Although these 'biners are smaller, they feature a large gate opening for smooth, efficient clipping, and the flared noses help prevent accidental openings as they scrape against the wall or catch our fall.
