For the 5'7" bed on the 2004-2014 Ford F-150, 2010-2014 Ford F-150 Raptor, plus the 2006-2008 Lincoln Mark LT (without Ford's Cargo Management System), this BAKFlip F1 is the matching hard folding cover. It brings a profile that sits nearly flush with the bed rails and EPDM seals with rounded hinges and drain tubes. It folds to open about two-thirds of the bed, or all of it when folded against the cab. Install is clamp-on, three or four clamps per side, with no drilling into the bed rails. Coverage is BAK's 5-year limited warranty from the purchase date.
