Snatch Blocks are an important tool for your winch recovery kit. The added peace of mind alone is a large enough reason to use one each time you use your winch. The Swivel Connection reduces stress to wire rope during use and can prolong the life of Wire rope. Always refer to the Working load limit (WLL) of your Wire Rope or Synthetic Rope and be sure your snatch block is equally rated. Snatch blocks also have a recommended size of rope to be used. This relates to the size of the groove in the Sheave and is extremely important in order to protect your rope from damage. This Snatch block has a 4:1 Design factor.
