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.

Process from ordering over phone to install was simple. Customer service handled with ease. Shipment arrived early. Cover was installed with little to no problem. Adjusted once to lower so side molding fit more snug on bed top. It sat in box for a month so this may be why it was not snug. The water tubing was to stiff. It pinched trying put into bed holes. Used soft hose from Auto store. The metal railing towards back of truck was razor sharp. Filed down. Took to carwash. Minimal leak. Love it.

complete junk

Received the cover and it appears to be made well. After the first heavy rain the cover leaked at all seams as well as the seals along the rail. I do not recommend this cover.. Customer support for the Undercover company also does not want to accept a return even though I only had the cover for two weeks they are only offering to send a new replacement and no refund. Autoanything is working on resolving the issue....

it is just what I was looking for.

The entire process was went very good, from ordering, getting a nice extra discount price with no tax, and then the install was very quick. There is a utube video that can be pulled up that shows the entire install. I did have to make a minor adjustment to get the overall fit right, but the installer will figure that out. I am very pleased at this point.

Great Product

This is designed for customer satisfaction and performance. I installed mine in less than 30 minutes. Packaging was great ... not a scratch or ding anywhere.
