The BakFlip FiberMax is essentially a cross between our popular BakFlip G2 tonneau cover and our flagship model, the BakFlip F1. The FiberMax, while lacking some of the refinement of the F!, makes use of all the features of the BakFlip G2, from its tough aluminum substructure, to its robust EPDM hinge design to it's functional and well built slam latch system. All features of the BakFlip FiberMax mirror those of the BakFlip G2. The only difference is that the top surface of the FiberMax is made from an impact resistant Fiberglass Reinforced Polymer (FRP), rather than aluminum. This difference appeals to people that live in areas that are subject to heavy snowfalls as well as hail. In addition, if you're the kind of person that is particularly heavy on your truck, the FiberMax will probably appeal to you. The BakFlip Fibermax is a hard folding tonneau cover that is most definitely a work horse. It has built in cab protection, is operable from either side of the truck, is equipped with slump latches under all panels and has a sleek, contemporary design. Every single last component of the BakFlip FiberMax is made in the USA. It is truly an awesome tonneau cover, that delivers everything you need, without breaking the bank. The BakFlip FiberMax is also designed to work with the BAKBOX, the CS rack system and allows full access to stake pockets.
