The MAXTRAX CORE SHACKLE is designed to be at the CORE of two interacting MAXTRAX Products. The CORE SHACKLE is designed for use with the MAXTRAX WINCH RING 120. The MAXTRAX CORE SHACKLE has been designed and tested as part of the MAXTRAX RECOVERY SYSTEM. The MAXTRAX RECOVERY SYSTEM is comprised solely of MAXTRAX products and has not been tested with any third party branded products. Critically, if the MAXTRAX RECOVERY SYSTEM is overloaded the MAXTRAX FUSE SHACKLE is designed to be the weakest link, and the expected point of failure. Accordingly, YOU MUST USE a MAXTRAX FUSE SHACKLE in the MAXTRAX RECOVERY SYSTEM during any vehicle recovery. Only use rated recovery points when connecting the MAXTRAX FUSE SHACKLE or MAXTRAX CORE SHACKLE to a vehicle.
