Key Features
- Aluminum-skinned panels. Lightweight yet sturdy, the matte-black coated aluminum top resists dents and maintains shape under pressure. Designed to support up to 400 lb evenly distributed.
- Carpeted under panels. Interior surfaces are finished with durable carpeting to protect tools and cargo from scratches and rattles.
- Automatic slam latches. Simply fold panels into place, the slam latch catches securely to the redesigned L-rail system, making operation quick and effortless.
- Built-in prop rods. Securely prop the cover upright for full-bed access, even while driving. No fuss, no tools.
- Dual-action tailgate seal. Whether your tailgate is open or closed, the seal locks tight to prevent water intrusion. Closing is smooth, without lifting the final panel.
- Weather-resistant system. EPDM rubber seals and hinge design block the elements; integrated drain tubes redirect water away from the bed.
- Flush, low-profile look. Clamps onto factory rails with a no-drill L-Rail system. Once installed, the tonneau cover blends smoothly with the truck’s factory lines.
