The Undercover Ultra Flex is constructed of aircraft grade aluminum panels that have been finished in a UV resistant, matte black powder coat. The Flex cover also has a BedRug carpeted finish under each panel. The Ultra Flex uses EPDM rubber seals and hinges so it provides maximum security from rain and snow, and the rails also aid drainage by channeling excess water through the provided drain tubes.
The Undercover Ultra Flex installs easily with no drilling thanks to the clamp-on design. You only need basic tools like a socket wrench to complete the installation on most vehicles. A great feature the Ultra Flex offers is the ability to gain full bed access without having to remove the cover completely. You 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 is the ability for the tailgate to close without first opening the cover.
