If you're in the market for sleek, stylish bed protection for your pickup, then consider the low-profile, color-matched aesthetic of a Fusion Tonneau Cover from UnderCover! This tonneau cover offers a classic tri-fold design, exceptional theft resistance, and professionally paint-matched top panels that blend seamlessly with the body of your pickup.

This tonneau cover features a rugged aluminum panel construction for maximum strength and theft resistance. Unlike theft-prone soft covers, the UnderCover Fusion is cut and slash-resistant, keeping the valuables in your truck's bed safe and secure. However, this cover doesn't only resist theft but also extreme weather conditions! Integrated EPDM rubber hinges and perimeter seals prevent moisture intrusion, protecting your precious cargo against heavy rain, dirt, dust, and other contaminants.

Aesthetically, this tonneau cover is tough to beat. Unlike most competitors, which feature a textured black finish that blends into the bed, the UnderCover Fusion features painted top panels that are professionally color-matched to your pickup's factory paint code, ensuring a flawless match that doesn't disappear into the bed but become a part of your pickup's body.

Operating the UnderCover Fusion Tonneau Cover is simple and intuitive. The classic tri-fold design features three panels and three sets of hinges, which allow you to fold the cover onto itself toward the bulkhead for bed access. Where most tri-fold tonneau covers only offer 2/3 bed access, the UnderCover Fusion features integrated support arms that enable you to secure the cover against the rear window/cab for complete access to your pickup's cargo space when loading oversized cargo.

UnderCover backs the Fusion Tonneau Cover with a 5-year structural warranty and a limited lifetime finish warranty. For additional product inquiries, reach out to our qualified sales staff.
