The BAKFlip F1 is a premium hard-folding tonneau cover from the experts at BAK Industries, offering a sleek, low-profile design, exceptional impact, theft, and moisture resistance, and a simple bolt-on installation ripe for DIY-ers. The BAKFlip F1 utilizes high-quality FRP (fiber-reinforced plastic) top panels. Not only is this material aesthetically pleasing, but also impact-resistant with its rigid high-density foam core! It can even withstand up to 400 Pound of evenly-distributed cargo. This cover features high-quality aluminum side rails for added strength and an easy clamp-on installation; when closed, the cover latches into the aluminum rails, preventing thieves from prying at the cover's sides for entry into the bed. This cover isn't only theft-resistant but also highly effective against rain and extreme weather! Wrap-around perimeter seals prevent moisture from slipping beneath the cover and bed rails, keeping your cover clean and dry. If any water happens to bypass the seals, it's directed into the aluminum rails and out of the integrated drain tubes. The BAKFlip F1 features a unique, ultra-low-profile design; when viewing your pickup from the side, the cover practically disappears into the bed rails. Operating the cover is quick and easy. Simply drop the tailgate, release the rear latches, and fold the F1 toward the bulkhead, exposing 2/3 of your pickup's bed. Once the panels stack on top of one another, secure the cover with the integrated buckle straps, and you’re set to drive! If full bed access is required, fold the cover toward the window and secure it with the integrated prop rods.
