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.
- The tailgate lock on the truck is what secures the bed. If your truck does not have a tailgate lock, the cover may be opened by opening the tailgate

I like the solid low profile cover. Easy to install, but it's leaking somewhere and I'm not sure if it's the seal or drain channels.

I agree with other's that an extra set of hands would be recommended, however I found a clamp worked ok. Directions for attaching the front part to the bed (directly under the back window) was not as clear as I think it could've been...had to call tech support....but that onlytook maybe 1 minute...counting from when i dialed the number until my question was answered!!!! I highly recommend this cover!
