Description

The BAKFlip Fibermax is a hard folding tonneau cover made from fiberglass-reinforced polymer (FRP) top panels and a robust aluminum substructure. It is engineered for exceptional durability, theft resistance, and UV resistance, making it suitable for areas with heavy snowfall and hail. The cover features an ultra-low-profile, flush-mount design for a sleek appearance. It offers full bed access by folding up against the cab and has a water drainage system to keep the truck bed dry. Installation is a simple clamp-on process that requires no drilling or modifications. It's compatible with BAKBOX and CS rack systems. Proudly assembled in Missouri and backed by a 3-year warranty.
