Features:
1. The black version has built-in ball bearings, wear-resistant, smoother, high speed, low noise, low friction coefficient, high load resistance coefficient; Red model without ball bearing
2. Movable side plate, smooth damping, smooth opening and closing, not easy to shake
3. Concave pulley, smooth and smooth, polishing process, make the rope better fit the pulley, and use it more smoothly without jamming the groove
4. The double pulley adopts the design of isolation plate, the two ropes will not be entangled with each other when in use
5. High-strength aluminum alloy material, good load-bearing capacity, wide range of uses
