The Undercover Armor Flex is a hard folding tonneau cover constructed of aircraft grade aluminum panels. A highly durable, matte black Line-X finish offers superior protection against scratches, while offering UV resistance. The Armor Flex uses EPDM rubber seals and hinges so it provides maximum resistance from rain and debris. The tonneau rails also aid in this by channeling excess water through the provided drain tubes, helping to keep your cargo safe from the elements. The Undercover Armor Flex has a simple installation with no drilling due to the clamp-on design. All that is needed are basic tools like a socket wrench to complete the installation on most vehicles. A great feature of the Armor Flex is the ability to allow full bed access without having to remove the cover. Simply fold the cover, panel by panel, to the front of the bed, then secure the prop rods that hold it in the upright position. The truck can safely be driven with the cover in this position at highway speeds. Another great feature of the Armor Flex tonneau cover is the dual action tailgate seal. This seal lets you close the tailgate without needing to open the cover, while also letting you close the cover without lowering the tailgate. The automatic slam latches open from either side of the bed, and automatically lock the cover as it closes. These features add a versatile action to the cover, making it simple to operate. Undercover protects this cover against any manufacturing defects for a period of 5 years.
