4 inch Stainless Steel Pulley
4 inch Stainless Steel Pulley. RA/SMC pulleys have the high quality and strength necessary for rescue systems. This pulley is ideal for usage in haul systems on the challenge course such as the pull up swing. The stainless-steel sideplates rotate, allowing the pulley to be attached to the rope at any point. The axle nuts are double locked to the steel axle and marked with a witness line to indicate any loosening. The heavy-duty, heat-treated aluminum alloy wheels combine lightweight with high durability.
