FACTOR55 Designs and Manufactures some of the best and highest quality recovery parts and accessories on the market. Using Closed System Winching, which is a winching technique using rigging comprised entirely of closed link hardware. The non-closable opening of common winch hooks prevents hooks from qualifying as securely closed links. Poorly constructed sheet metal safety latches of hooks do not qualify as a secure means to contain loads and are prone to failure, especially during momentary slack conditions where winch loads often shift and apply high forces to these weak non-structural latches. Hooks often come loose during vehicle recovery operations due to hook safety latch failures.
