Extang Trifecta tri fold truck bed cover part # 44420 is a black leather grain vinyl cover with an aluminum frame and a unique hinge system that allows the cover to be folded up to 1/3rd its full size. Extang Trifecta tonneau covers are America's best selling style of truck bed cover because they are the easiest to install, just as easy to operate, and are the most versatile. We sell the Extang Trifecta cover over the cheaper knock offs because it has a better hinge system. better latches, and the best foam seals. The clamps, hinges, and frame all store neatly on the cover so it ships out completely assembled making installation a simple one man job that only takes 5 minutes. The tailgate has to be lowered to open the cover so if the tailgate is locked the entire bed is locked.
