Description

Measure Your Truck Bed for a Tonneau Cover

Does your truck have a track system?

  • Panels constructed of aluminum with an FRP coating on top
  • EPDM seals provide maximum water resistance
  • FRP exterior panel stays cooler to the touch
  • Holds 300 lbs evenly distributed
  • 3 year warranty
  • Made in the USA

The Undercover Flex is constructed of Fiberglass reinforced polymer and aluminum. The aluminum provides structure and rigidity while the fiberglass reinforced polymer protects against scratches and dents. The Flex also utilizes EPDM rubber seals and hinges so it provides maximum security from rain and snow.
The Undercover Flex installs easily with no drilling thanks to the clamp-on design. You only need basic tools like a socket wrench to complete the installation on most vehicles. One of the best features the Flex offers is the ability for you to gain full bed access without having to remove the cover completely. You simply fold the cover panel by panel to the front of the bed, then attach the prop rods to secure it upright position. The truck can safely be driven with the cover in this position at highway speeds.
Undercover warrants this cover against any manufacturing defects for a period of 3 years. The cover also is made in the USA so you can rest easy knowing the quality is second to none.

2014 RAM 2500, 6ft bed. Installation was easy, took me about an hour by myself. Follow the instructions until you get it all put together. I found it was easier to adjust once the cover was on I could lower the rails to get it to sit flush on the bed rail. To do this just install the cover per directions but leave the clamp bolts loose enough to where you can still move them a little, adjust the rails however you want. I have gotten some water in from the cab corners where it did seal all the way but the water just runs down the sides of the bed, no water in the middle of the bed and it wouldn't be enough to damage anything anyways. I like that you have to open the tailgate to open the cover and the release cables are nice and always pull. The thing I like most about this cover is the support rods, I didn't want something laying against my back glass so this was a no brain choice for me! The finish does scratch off rather easily so watch what you lay against it. Overall I love this cover and will definitely buy one for my next truck!
