Description
Protect your truck bed with the TrailFX TFX3706 Premium Hard Folding Tonneau Cover, designed specifically for select 2017–2021 Ford F-250 and F-350 Super Duty models. This hard tonneau cover features a durable aluminum construction, smooth matte black finish, and a clean low-profile design that enhances the appearance of your truck while helping shield cargo from weather and road debris.
The three-panel folding design provides convenient access to the truck bed without requiring complete cover removal. The cover folds toward the front and mounts on top of the bed rails using a clamp-on installation system, allowing installation without drilling. Mounting hardware is included, and the cover is compatible with bed rails and bed caps. A carpeted underside and finished tailgate edge provide a refined appearance while helping protect the bed and cargo from contact with the cover.
Built for practical everyday use, the TrailFX TFX3706 includes integrated lights for improved visibility and a secure locking design for added cargo protection. Its aluminum frame and cover offer dependable strength without an electric operating system or support battens. The cover is not compatible with tool boxes, ladder racks, or headache racks, making it an ideal choice for trucks with an open bed configuration. Fitment includes select 2017–2021 Ford F-250 Super Duty and Ford F-350 Super Duty models. Professional installation is not required, though verifying vehicle fitment before purchase is recommended.
