The Rugged E-Series hard fold tonneau cover is a quick and inexpensive solution to securing your truck bed. The cover is constructed of aluminum panels with an aluminum frame that has been powder coated for durability. The hinges also have a double layer seal to help keep water out of the bed. The installation is very simple on the Rugged E-Series hard folding truck bed cover. The cover arrives fully assembled inside the box so you just remove the packing material, set it on the truck, then fasten the clamps and you are ready to go. Because the cover sits on top of the bed caps the cover acts like an umbrella to keep water out of the truck bed as much as possible. The Rugged Liner E-Series hard fold tonneau cover is warranted against any manufacturing defects for a period of three years so you can rest easy knowing your investment is protected.
