Total Access. Patented Security. Ultra Protection. The RealTruck(R) UnderCover(R) Ultra Flex hard-folding tonneau cover is built stronger and more durable, engineered for heavy-duty use with a sturdy, premium-grade matte black aluminum surface and a high-density polymer core. Its low-profile design sits nearly flush with the bed rails for a sleek appearance and up to 400 lbs. of weight capacity (evenly distributed). With ultra details, inside and out, the Ultra Flex's underside looks just as good as its top. The smooth, matte black finish delivers a refined look, while the exclusive soft-impact underside adds a padded layer of protection for shifting cargo. The Ultra Flex fits tighter to keep water out. Upgraded seals and all-new tight-fit clamps provide state-of-the-art weather protection, keeping out water, dust, and debris—even in harsh conditions. Security is a hallmark of any high-end tonneau cover, and the Ultra Flex delivers. With a patented rail and clamp system featuring automatic slam latches, the cover automatically locks down every panel when closed to keep gear secure and out of sight—that's patented security you can trust. The RealTruck UnderCover Ultra Flex hard-folding tonneau cover delivers 100 percent bed access—all the time. Simply fold the cover to the cab, secure it in place, and safely drive with the cover fully open. When closed, the slam latches reengage automatically. Installation is fast and straightforward with UnderCover's all-new click-in design. The redesigned Tip-and-Click mounting system requires no tools, no hassle, and installs in under 30 minutes. Proven for extremes from Alaska to Florida, Ultra Flex has been tested in harsh conditions ranging from -40 to 180F and up to 95 percent humidity. It's also been tested for 7,500 hours to reliably perform for over a decade of driving. Backed by a 5-year warranty, the Ultra Flex is tough enough for the job site, sleek enough for daily driving, and secure enough to protect what matters.
