Ultralight Power Cams are the lightest 4-cam units in the world! Direct Axle Technology allows for more placement options in shallow, narrow, or bottoming placements, and makes tricky placements easier due to better cam lobe visibility. Range Finder tells you at a glance if you've chosen the right size cam for the placement. Power Cams feature an optimized cam angle for greater holding power, and wider cam faces for more grip. The U-shaped body provides greater durability and unparalleled control during placement and retraction. CNC machined for much greater precision than stamped or extruded cams.
