A functional and versatile knot-passing and high-strength tie-off pulley. The rigging holes allow for optimum separation of tag lines and hoist ropes for reeving variations. A greater spread between hoist pulleys reduces the chance of spinning of the load. Separate rigging holes for easy rigging and prevents karabiners binding against each other. The integrated sheave-lock pin inserts from the stowed axle position. Anodized aluminium sheave with sealed ball bearings for long wear and high efficiency.
