The FlatLink E (Expert) is a variation of our popular foldable standard FlatLink winch shackle mount. The FlatLink E provides a means to eliminate the conventional winch hook and replace it with a safer and more secure screw pin shackle resulting in a CLOSED SYSTEM WINCHING operation. The large pear shaped shackle mounting hole allows for attachment to either the pin or bow end of common screw pin shackles, as well as common OEM recovery points. This makes the new FlatLink E more versatile than the current FlatLink design, but it also adds the possibility of a dangerous shackle side loading condition (See Picture), especially during momentary slack conditions. A shackle side loading condition is not possible with our standard FlatLink shackle mount due to the shackle pin mounting constraint. For the recreational off roader we highly recommend the safer standard FlatLink product, not the FlatLink E. This way the winch operator does not have to monitor whether the shackle may have shifted and rotated in the recovery tackle.
