New Technologies: Rounded inner edge for less wear on carabinersGeometry directs the carabiner for optimal orientation on overhangs.Conical WasherAnti-rotation dimples are now smaller and spaced further apartOptimized surface area contact with the rockFeatures: Minimum Breaking strength: 25 kN / 5620 lbsCE Certified: EN795:2012; EN959:2018Diameter: 3/8in and 1/2in.Weight: 57g (3/8), 56g (1/2)316L Stainless SteelMade in Barcelona, Spain316L Stainless Steel: Perfect for all outdoor uses except in the most corrosive environments where Titanium is the only long lasting option. 316L steel is a marine-grade stainless steel with exceptional corrosion resistance. Conical Washer: The rim of the bolt anchor hole protrudes slightly into a conical shape, away from the wall. The act of pulling the bolt anchor will generate a spring effect that provides constant pressure against the wall, multiplying the strength of the torque. It also provides more consistency when torque tightening the bolt. Lighter: With a thickness of 3.5mm (previously 4mm) we have reduced the weight of the hanger by 12.5% while still being one of the most robust hangers on the market. Anti-rotation Pins: Textures on the hanger help to reduce the likelihood of the hanger spinning. Geometry: When placed on a roof, the carabiner will be routed so that it never comes into contact with the projecting head of the bolt anchor.
