PARTNER pulley-used to reduce the effort needed for a self-rescue or in a hauling system; swinging side plates allow for quick, easy installation on the rope; sheave mounted on sealed ball bearings provides excellent efficiency. TIBLOC ascender-replaces the prussik or rope clamp in a hauling system or the self-locking knots in a self-rescue; angled teeth and self-cleaning slot ensure good grip on frozen ropes. Two OK SCREW-LOCK carabiners-perfect for use with the PARTNER and MICRO TRAXION due to their self-centering symmetric shape.
