Black Diamond Camalot C3 Cams With up to 30 percent less head width than any other micro cam, C3 Camalots fit in more places, more securely. The C3's broader middle lobe overlaps and interlocks with the opposing cams, maintaining the cam head's narrow width and maximizing contact area. Three compression springs independently drive each cam for increased holding force and contact in irregular placements. Their unique thin profile stems are laterally stiff for slotting in tight placements, but flexible over edges for a more evenly dispersed load. Easy to grab, even with gloves on, their cable loops provide ample room for clipping in short or with a draw. The runner has been sewn on in a way to keep one side permanently near the cam for consistent loading. The trigger has holes in it making it easier to retrieve with a nut tool. Solid wire construction helps to keep placements from making any awkward loadings for the cam. The three lobe cam structure has a solid when open construction for added protection. a Averaging 30% narrower heads than any other 3 or 4 cam units on the market a Patent pending interlocking cams allow for solid placements in narrow constrictions and pin scars a Patent pending compression drive springs push each cam indepently with greater force so they hold better in tough placements a U stem design provides a balanced combination of stiffness and flexibility a Ribbed trigger and thumb rest improve handling when you're really pumped a Color coded units and slings for quick and easy ID Size Color Range mm Weight g Strength kN 000 Gray 7.8 12.2 54 4 00 Purple 9.0 13.7 56 6 0 Green 10.7 15.8 59 7 1 Red 12.6 19.2 63 10 2 Yellow 15.9 23.6 67 10 Note that this item of climbing safety equipment is non returnable.
