When it comes to gymnastics, politics and truck bed cargo control-flexibility is key. And, there's no better way to touch your cargo-covering toes than with the Undercover Flex Tonneau Cover. Undercover's first folding tonneau features a sleek, low-profile design that folds away to reveal your entire truck bed.

Featuring 3 folding panels, the Flex cover folds completely forward and back to deliver full bed access and maximum security. The low-profile design sits flush with your truck's bedrails for a super sleek and slippery style that improves MPG, too. And, thanks to the simple clamp system, the Undercover Flex is easy to install and remove with no drilling required.

Crafted from a fiberglass reinforced polymer with a subtle textured finish, the Flex shoulders up to 400 lbs. And, it'll never crack, warp, fade, rust or corrode. Connected by seamless leak-proof rubber seals and featuring an integrated drain tube, the entire assembly keeps your bed clean, dry and secure. Best yet, Undercover backs your Flex Tonneau Cover with a 3-year warranty.

Undercover Flex Tonneau Cover

Installation was pretty easy, with the exception of the drain tubes. Why they are made from rock hard plastic baffles me. Seems to be totally water tight. No red handle on last panel as noted in every video. Installed over a bedrug. Completely could sleep in there! Shipped quick, 2 or 3 days. Looks really smooth and nice. Opens and closes easily.

couldn't have gotten it any cheaper anywhere. Locally it was overpriced and they have the same factory product for less and the shipment was quick. Thanks again auto anything.

Ordering was made very easy by Derek, he answered all my questions and assisted me placing my order. Arrived a day early. My daughter and I installed in about thirty minutes it was very easy, we watched a youtube video first. It actually took us longer to find the drain holes in the truck bed than it did to install. I purchased in January and we have had snow and rain every week no leaks and went through car wash and still no leaks. I have received many compliments. High quality product.

very nice
