Great looks, great security, full truck bed access and the most cutting edge tonneau cover design and styling available anywhere in the world. Best of all, the BakFlip's patented design offers the world's only hard flip style tonneau cover that guarantees access to your entire truck bed. Designed for people that are particularly hard on their folding tonneau covers or who live in climates that are subject to a lot of hail, ice and snow, the BakFlip F1 is made from materials that are virtually indestructible and is much stronger than the body of your pickup truck. It will never dent through normal daily use, even when you drop something heavy on it or get caught in a severe hail storm. The flip style tonneau cover can support over 300 lbs on top when closed.
Staying relatively cool to the touch, the fiberglass reinforced polymer top surface will not heat up like aluminum and has a transparent coat which protects it from fading. The BakFlip F1 is completely UV resistant and will remain looking as good in 5 years as it does the day you put it on your truck. The aluminum substrate of the BakFlip F1 tonneau cover will never expand and contract, so as far as structural stability, The BakFlip F1 performs just like you want-PERFECTLY!
