What Is Closed System Winching?
Closed System Winching is a winching technique using rigging comprised entirely of closed link hardware. The non-closable opening of common winch hooks and poorly constructed sheet metal safety latches do not qualify as a secure means to contain loads and are prone to failure. During momentary slack conditions where winch loads often shift, recovery ropes may endure high forces and hooks often come loose during vehicle recovery operations due to hook safety latch failures, causing safety concerns.
Factor 55 FlatLink E addresses this winch safety issue by providing a secure screw pin shackle mounting interface to all steel winch cables and synthetic winch ropes. The Factor 55 unique double shear pin design provides a simple, trouble-free method of attaching existing cable and rope eyes to the FlatLink E. This provides a precision mounting hole for screw pin shackles and also provides a large rubber-protected flat surface to cushion against all fairlead mounting surfaces.
