Bakflip Tonneau Cover For Rambox. This is similar to the cover BAK48311 that you referenced but that one is for long bed Ford pickups. Here are some pics of the installed cover.
All the greatest features of the BakFlip including full access to your bed. When ordering the RamBox part numbers the RamBox rails need to be the OEM factory silver cargo rails not black to function properly with our covers 448227RB Reg. If you are looking to provide your truck with better protection and more security a BakFlip tonneau cover is a great investment.
The BAKFlip G2 is the smartest investment when you need full bed access and maximum cargo protection.
The BAKFlip F1 secures the bed and locks with the OE tailgate. The BAKFlip F1 is built to last with its upgraded latch housing heavy-duty hardware and components. There is about 575mm or more of space between each cover section and the rails on each space total of 115mm or just under 12 inch of space which allows the cover to slide back and forth. For a compatible ladder rack that works with the BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish BAK448227 for the 5-12 foot bed without Rambox and BAK448223 for the 6-12 foot bed without Rambox I recommend the Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars - 500 lbs A70450 for 5-12 foot.
