Product details:

A combination of CNC machining, Dyneema slings, and a direct-axle design that eliminates all unneeded material ensures that you're not carrying one extra gram. Metolius takes climbing safety seriously, which is why it added cam stops for better holding power in tipped-out or even passive placements. Not wanting to stop there, Metolius also added rangefinders on the sides of these cams to help you verify that you have exactly the right size for the crack in question.
