Design and Details Direct Axle Technology (DAT) makes Ultralight Power Cams the lightest 4-cam units in the world DAT allows for more placement options in shallow, narrow, or bottoming placements DAT makes tricky placements easier due to better cam lobe visibility, especially in the small sizes 13 mm (0.51") Monster Sling webbing Range Finder tells you at a glance if you've chosen the right size cam for the placement Optimized cam angle for increased holding power Wider cam faces for more grip U-shaped body for greater durability and unparalleled control during placement and retraction Machined cam stops Color-coded sewn slings and tubing CNC machined for much greater precision than stamped or extruded cams 7075-T6 aluminum (sizes #00-6) 6061-T6 aluminum (sizes #7-8) CE/UIAA certified Hand built, inspected and individually proof tested in Bend Oregon Range: 0.34 - 0.47" / 8.5 - 12 mm Strength: 1100 lbf / 5 kN Weight: 1.6 oz / 45 g SPECIFICATIONS for 0 Range: 0.39 - 0.59" / 10 - 15 mm Strength: 1100 lbf / 5 kN Weight: 1.7 oz / 48 g SPECIFICATIONS for 1 Range: 0.49 - 0.71" / 12.5 - 18 mm Strength: 1800 lbf / 8 kN Weight: 1.9 oz / 54 g SPECIFICATIONS for 2 Range: 0.62 - 0.89" / 15.5 - 22.5 mm Strength: 2250 lbf / 10 kN Weight: 2.3 oz / 64 g SPECIFICATIONS for 3 Range: 0.74 - 1.04" / 18.5 - 26.5 mm Strength: 2250 lbf / 10 kN Weight: 2.4 oz / 68 g SPECIFICATIONS for 4 Range: 0.93 - 1.32" / 23.5 - 33.5 mm Strength: 2250 lbf / 10 kN Weight: 2.7 oz / 77 g SPECIFICATIONS for 5 Range: 1.01 - 1.56" / 28 - 39.5 mm Strength: 2250 lbf / 10 kN Weight: 3 oz / 86 g SPECIFICATIONS for 6 Range: 1.28 - 1.89" / 32.5 - 48 mm Strength: 2250 lbf / 10 kN Weight: 3.5 oz / 98 g SPECIFICATIONS for 7 Range: 1.57 - 2.26" / 40 - 57.5 mm Strength: 2250 lbf / 10 kN Weight: 4.5 oz / 127 g SPECIFICATIONS for 8 Range: 1.91 - 2.81" / 48.5 - 71.5 mm Strength: 2250 lbf / 10 kN Weight: 5.3 oz / 150 g
