NEED MORE POWER, ADD A PULLEY
Multiply your pulling power by two, three or four times using pulleys. You can also use them to change the trajectory of the rope or the pulling angle! Their oscillating plates eliminate the need to thread the rope and allow them to be installed very quickly. In addition, they prevent the rope from coming out once closed. Finally, the self-locking pulleys help retaining a load, which comes in very handy in many situations.
