Easier handling: sheave mounted on sealed ball bearings for excellent efficiency gate opening on the pulley side facilitates installation of the rope when the pulley is fixed to the anchor may be used with a CAPTIV positioning bar to favor loading of the carabiner along the major axis and to limit the risk of it flipping Keylock system prevents any accidental snagging of the carabiner when putting the pulley in place H cross-section of carabiner: ensures an improved strength-to-weight ratio protects markings from abrasion Technical Specifications Rope Compatibility 7 – 13 mm Maximum Working Load 4 kN (2 x 2)Efficiency 85%Major Axis Strength20 kNMinor Axis Strength8 kNOpen Gate Strength 7 kN Certifications Triact-LockNon-LockingCE EN 362CE EN 12275EN 12275EN 12278EN 12278UKCAUKCAEACEAC
