Introducing the next generation of folding covers -- the UnderCover Flex folding cover. Flex combines the best of both worlds, the security of a hard locking cover and convenience of a soft roll up cover. Constructed from the best materials available, Flex will withstand the abuse Mother Nature throws at it and keep coming back for more. Low Profile -- Ultra-low profile design rests inside the bed rails allowing for a very sleek look. Full Access -- Built in prop rods secure the cover allowing your truck to be driven with the cover fully open. Easy Removal -- Entire cover can be removed in seconds with no tools needed. Secure Design -- Plastic buckles and straps are included to secure the panels in the partially open position. FRP Composite Panels -- Lighter, stronger and higher dent resistance than aluminum. Weather Resistant -- Rubber seals and drain tubes channel water away from and out of the bed. Easy Clamp-on design. No other folding cover can match the Flex for versatility, security and function. Covered or uncovered, always an option with UnderCover.
