      Description

      Reliable Cargo Protection. For reliable and efficient truck bed protection, this Black Textured UnderCover Flex Tri-Fold Tonneau Cover stands above all other aftermarket products. Harsh weather conditions can do serious damage to your cargo when left out in the open. Fortunately, this UnderCover Flex Tri-Fold Tonneau Cover comes with impenetrable rubber seals and drain tubes to keep water away from your cargo. A tailgate lock ensures that when your Super Duty’s tailgate is closed no one will be able to open this tonneau cover.

      Versatile Tri-Fold System. Whether you’re carrying small or large items, this UnderCover Flex Tri-Fold Tonneau Cover has your back. The advanced tri-fold system lets you open the cover one panel at a time. If you only need the rear part of the bed, you can lift the rear part of the cover only. For full bed access, fold this cover all the way to the cab area where you can secure them with prop rods.

      Solid Construction. A tonneau cover is only as good as its construction, which is why the cover part of this UnderCover Flex Tri-Fold Tonneau Cover is made from fiberglass reinforced polymer. This gives the cover significant resistance against heavy loads, impacts, and puncturing. The tonneau frame is constructed from tough aluminum alloy for added durability and is coated with a black textured finish for all-around corrosion protection.

      Hassle-Free Mounting Process. Installing this UnderCover Flex Tri-Fold Tonneau Cover is quick and simple. The entire tonneau cover mounts directly on your Super Duty’s truck bed without the need for drilling.

      Warranty Support. UnderCover warrants that this Flex Tri-Fold Tonneau Cover is free from material and workmanship defects for a period of 3 years. For the complete breakdown of warranty coverage and exclusions, please check the manufacturer’s website.

      Application. This Black Texture UnderCover Flex Tri-Fold Tonneau Cover will fit all 2017-2024 Ford Super Duty F-350 models with 6.75-foot beds.

          Word on the Trail

          I'm a new & reluctant customer. So I contacted by phone & chat with several different questions about a product I needed to order. They were very knowledgeable about the product. I was given nothing less than the most professional assistance EVER, both times. I WILL be a returning customer.
