The Piu 2.0 uses a variable notched design with smooth teeth on the brake side of the device to lock onto ropes with more friction than other tube-style devices. Other features include the ability to set up the device in auto-block mode for belaying two seconds and a large rigging hole that allows a locking carabiner to rotate all the way through. The Core Lock is an extremely smooth HMS belay and rappel carabiner with a secure screw lock closure. ------ HMS carabiner Camp Core Lock The unique shape of the Core Lock HMS carabiner creates a very wide gate opening and positions ropes for the smoothest belays and rappels. The proprietary SphereLock nose makes clipping ropes and webbing easy. * Extremely smooth HMS belay and rappel carabiner with secure screw lock closure * New screw gate is lightweight and easy to handle * Large gate opening and proprietary SphereLock nose make clipping ropes and webbing easy * Laser etched marking to indicate if the lock is open or closed Specifications: * Weight: 81 g, 2.9 oz * Gate Opening: 27 mm * Major Axis: 23 kN * Minor Axis: 11 kN * Open Gate: 6 kN * Size: 114x77 mm Certifications: EN 12275/H, EN 362/B, UIAA ------ The Più 2.0 has been designed to deliver optimal performance with the new generation of skinny ropes that have gained popularity in recent years. Using a variable notched design with smooth teeth on the brake side of the device along with narrower slots for the rope, the Piu 2.0 locks onto skinny ropes with more friction than other tube-style devices. Other features include the ability to set up the device in auto-block mode for belaying two seconds, a large rigging hole that allows a locking carabiner to rotate all the way through, a specially shaped hole that captures the nose of a keylock carabiner (specifically designed for use with the HMS Nitro and HMS Compact Lock carabiners) which can then be used as a lever for releasing tension if a second locks the device in auto-block mode, and a diagonal cable that prevents the rope from rubbing and jamming. * Specifically designed for use with skinny ropes * Can be rigged in auto-block mode for belaying two seconds * Diagonal cable prevents the rope from rubbing and jamming Specifications: * Weight: 80 g / 2.8 oz * Rope diameter (double): 7.6-9.0 mm * Rope diameter (double): 8.9-11.0 mm Certifications: EN 15151-2, UIAA
