A unique passive camming devices that will fit in narrow slots where most other cams won't go. Designed by the famous Lowe brothers tri-cams retain a simple, lightweight functionality, especially in snowy, icy, scary situations. Tri-Cams are also immensely strong when compared to similar sized cams. They work amazingly well in pockets, pin-scars and are perfect for shot-holes in quarries (Masters Edge anyone? You'll need a 2.5). A tri-cam also remains effective in icy conditions.
