http://www.treestuff.com/store/catalo... This special auto-locking carabiner is the perfect solution for a compact mechanical advantage system. It features two integrated pulley sheaves with high-efficiency roller bearings. The captive bar is threaded and removable, and the spine is uniquely shaped to maintain the correct orientation. It also features a full-strength becket that is oriented 90° from the carabiner to reduce interaction between running ropes and any becket connection.
