Petzl Rollclip A - Triact-lock Pulley-carabiner Rollclip A is a pulley-carabiner with a gate opening on the pulley side that facilitates installation of the rope when the pulley is connected to the anchor. It is available with an automatic TRIACT-LOCK locking system. The ROLLCLIP A may be used with a CAPTIV positioning bar to favor loading of the carabiner along the major axis, to limit the risk of it flipping and to keep it integrated with the device. The ROLLCLIP A pulley may be used as a directional point on the lower attachment point of the ASCENSION handled rope clamp, for short rope ascents. Gate opening on the pulley side facilitates installation of the rope. The ROLLCLIP A pulley can be used as a directional point when combined with the RESCUCENDER rope clamp. Features: 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 Automatic TRIACT-LOCK locking system Technical Specifications: Material: aluminum Locking system: TRIACT-LOCK Weight: 115 g  /  4.05 oz Certification(s): CE EN 362, EN 12275, EN 12278, EAC Gate opening: 22 mm  / 0.86 in Min. rope diameter: 7 mm  /  2.75 in Max. rope diameter: 13 mm  /  0.5in Sheave diameter: 18 mm  /  0.71in Maximum working load: 2 x 2 = 4 kN Efficiency: 85 % Major axis strength: 20 kN Minor axis strength: 8 kN Open gate strength: 7 kN
