We will continue to support the TT 12E gates in the future, but new gates cannot be ordered after 12/31/2017.

The THIEMAN TT-12 Series is completely assembled into one compact unit – ready to run. Simply bolt or weld it to the truck bed and connect the battery cable. Installation is fast and easy. And years from now, it will be just as simple to remount the TT model on a new truck. The lifting mechanism is completely enclosed for a neat appearance and protection from the elements. The towing rated swing-away bumper is also standard on the TT-12. The THIEMAN TT’s overall design makes it the toughest liftgate available in its class.
