A hard folding truck bed cover that comes with overwhelming new features and is topped off with an alluring matte finish. The Ultra Flex is in a category of its own. From the irresistible outward appearance to each component beneath the cover, the Ultra Flex has been carefully crafted to be the ultimate all-purpose truck bed cover.
All-new features that accompany the Ultra Flex include an integrated luminous rail light system for enhanced night vision, and a dual action tailgate seal, allowing for easy operation and you to close the tailgate with the cover-up or down. Multiple riding positions allow the user to ride with full access to their bed, and full weather protection is available if the cover is in the fully closed position.
Ultra Flex is an easy clamp-on application and can be installed and removed easily with our newly designed L-Rail’s. What’s more, the Ultra Flex is backed by a 5-year warranty, making it the most desirable folding cover on the market.
Great fit on my 2020 f150 short bed. Installed it in about an hour. Probably a thirty minute job, but I check and double check. Good fit.
Easy to install and looks great.
I researched and debated at length regarding a tonneau for my 2018 F-150 Lariat. When I finally decided on this one, TonneauCovered was on the spot to hook me up with the best price and super fast shipping. The quality of this tonneau is top-shelf. Very solidly built. Installation was straightforward and took maybe an hour from the time I opened the box. Once you've installed the rails, be sure to carefully line up the cover at the bulkhead, as this will save some alignment and latching issues. I haven't yet had a chance to test its resistance to weather, but it has done a great job of keeping our gear reasonably dust-free, out of the sun, and away from prying eyes. Kudos to UnderCover for a well-engineered tonneau!
