BAKFlip Fibermax Hard Folding Tonneau Cover by BAK Industries

The BAKFlip FiberMax combines aluminum construction with Fiberglass Reinforced Polymer panels for superior dent and scuff resistance while staying cooler to touch. Its robust hinges and slam latch system ensure reliable operation. The reinforced structure supports up to 300 pounds evenly distributed, ideal for transporting construction materials. The low-profile design features textured gloss-black panels that resist environmental damage better than soft covers or aluminum alternatives.

Key Features

FULL BED ACCESS - Fold the cover up to the cab for full-bed access without removing the cover. Rubber bumpers protect the cab from impact.

WATER DRAINAGE SYSTEM - The rails collect and guide water to the front of the bed where it is emptied through drainage tubes

NO DRILL CLAMP - The FiberMax can be installed in less than an hour without drilling into the truck bed.

PREMIUM WEATHER SEALS - Weather resistant and extremely durable seals made of EPDM form a tight seal to the bed rails. Rounded style hinges help prevent water and debris from entering the truck bed.

TEXTURED FRP TOP PANEL - Fiberglass Reinforced Polymer top panel with a textured finish and a powder-coated aluminum bottom.

EASY OPERATION - Each panel automatically latches to the covers mountings rails as the cover closes. Latches deactivate with a simple pull of the cable.
