The THIEMAN TT-16/20 is completely assembled into one compact unit – ready to run. Simply bolt and/or weld it to the truck bed and connect the battery cable. Installation is fast and easy. Plus years from now the TT-16/20 will be just as simple to remount onto a new truck. The lifting mechanism is completely enclosed for a neat appearance and protection from the elements. The large platform makes awkward material a breeze to load and unload. The TT-16/20 overall design makes it the toughest liftgate available in its class.
