If you're seeking a reliable tonneau cover that can give you easy access to the truck bed and at the same time provide excellent cargo protection, this product is the right option. The cover boasts of the simple things and simple details that turn it into the next generation of folding tonneau covers. Featuring an ultra-low profile design, the Flex cover rests inside the bed rails and definitely adds to the truck's appearance. The panels of the cover have a three-layer construction: the core material is expanded polystyrene that is sandwiched between the top and bottom layers of fiberglass reinforced polymer. The applied materials make the cover extremely lightweight, as well as dint- and rust-resistant.

Even though the Flex cover is one of the lightest tonnos in the industry, it is strong enough to support up to 400 lbs of evenly distributed weight. The panels are treated with a UV inhibitor, so the finish will never fade. And even if you happen to get caught in the rain, your cargo will be securely protected since the rubber seal and drain tubes will channel water away from and out of the bed.

Perhaps one of the main benefits of the Flex cover is that it installs a lot faster than any other tonno out there. Even if you already have bed extender or any factory cargo management system, this cover will fit and work just great. It will come with a complete hardware kit: two rails, clamps that are unique to your truck, mounting bolts, installation guide, and warranty instructions. Basically, the only tool you will need is a 9/16 wrench, and there will be no drilling involved.

You can fold your cover all the way to the cab and then secure it with the convenient prop rod to get full bed access. The great thing about Flex is that it doesn't actually come into contact with the cab, so there will be no damage caused by friction. And if you want to secure the panels in the partially open position, you can use the plastic buckles and straps that are included with the cover. All Flex covers are proudly manufactured in the USA and carry a 3-year warranty.

Warranty Information

Find out everything you need to know about the product warranty

TERMS OF THIS WARRANTY:
UnderCover, Inc. warrants the FRP structure of your Flex Cover to be structurally free from defects in material and workmanship for (3) three years from the retail date of purchase. The hinges, seals, and hardware are warranted to be free from defects in material and workmanship for (3) three years from the retail date of purchase. This warranty applies only to the original purchaser and is nontransferable. Your original sales receipt will serve as proof of purchase for this warranty. Before credit can be issued on a warranty claim, proof of defect may be required. This can be determined at the time of the claim.

EXCLUSIONS OF THIS WARRANTY:
Not covered under this warranty is failure due to neglect, improper installation including any modifications to installation hardware, alterations, addition of equipment, abuse, accident, weather related damage, exposure to chemicals that are not labelled “safe for rubber” and normal wear from lack of maintenance.

CAUTION:
Always read the ingredients of any product you are using to clean your Flex Cover. Make sure that you use only products that are safe for use with rubber. Many chemicals contain material that will permanently discolor or damage your Flex Cover hinges and seals. This is not considered a manufacturer defect.

OWNER RESPONSIBILITIES:
Incidental or consequential damage or loss of contents due to use, neglect, lack of maintenance, misuse or abuse of the Flex Cover is the sole responsibility of the truck owner and operator. Paint damage to your truck is not covered under this warranty. When operating your truck always keep the Flex Cover in either the fully closed and latched position, or one of the two approved open positions. The first approved open position would be the first, second, and third panel stacked onto the forth panel and the buckles must be secured together. The second approved open position would be all four panels standing up vertically behind the cab. In this position both prop rods must be attached and the buckles secured. Do not operate the truck at excessive speeds with the Flex Cover in either open position.

REPAIR AND REPLACEMENT:
In the event that your Flex Cover is found to be defective under the terms of this warranty, it is at the discretion of UnderCover, Inc. to repair or replace the defective part. All repairs must be made under the direction of UnderCover Inc. UnderCover Inc. is not responsible for any transportation costs associated with the warranted claim.

MAINTENANCE & CARE:
The FRP panels of your Flex Cover require only periodic cleaning with mild car wash soap. Avoid use of all abrasive type cleaners as they may dull the finish. Some chemicals and fluids such as insect repellents, oils, solvents, and lubricants could potentially damage the rubber hinges and seals and void the warranty.

Magnuson-Moss Warranty Act:
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More

Great Tonneau Cover!
This cover looks great on our new F-150! We love that it can be opened all the way and that our stuff is locked away when it is closed out of sight, out of mind! Installation took us longer than we expected. We had a couple of questions about the installation so we looked for and found several YouTube videos that helped. All in all, installation was easy enough. We had a heavy rain yesterday and there were no leaks! We're happy we got this cover!

Exceeds All Expectations
This tonneau cover has definitely exceeded my expectations. It is a high quality product, installs with ease (45 minutes), and looks great on my truck. It's also quite waterproof as we've had several drenching rainstorms since installing it, and the contents of the truck bed remained bone dry. I would definitely recommend this tonneau cover to anyone looking for one.
