The snatch block is a pulley system with covered and protected yet removable sides. It is possible to unscrew or remove one side, slip in the winch cable or rope, and then re-protect the same side to prevent the cable from leaving the groove. It has either a hook or a shackle at it’s tip. Snatch blocks or pulleys are used to change the direction of the pull to a different angle relative to a fixed point. They are also used to create more complex pulley structures and gain mechanical advantage. A pull of 10 lbs can be changed to a pull of 80 or even 800 lbs depending upon the mechanical advantage offered by the pulley structure.
