Everyday quality Snatch Block with Shackle. Ideal for vehicle recovery and off road applications where a steel wire rope cable needs to be directed via a pulley wheel. Sheave Size: Varies From 3" to 4.5" Wire Rope: 3/8" through 1/2" Working Load Limit: Up to 4.5 Tons The snatch block is a pulley system with covered and protected yet removable sides. 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.
