Pulleys are removable for easy installation. Compared with other pulleys, the pulley wheel support plate is thicker, providing stronger wheels and increased load capacity. Made of stainless steel, rust-proof and corrosion-resistant, suitable for outdoor use without risk of pulley corrosion. The thickened steel plate bracket and wheel core enhance the load-bearing capacity. Each small pulley can support up to 660 lb (300 kg). Equipped with two carbon steel ball bearings to reduce wheel friction, ensuring smooth, quiet operation.
