Built for the 6'6" bed on the 1988-1998 Chevrolet and GMC C/K 1500, 1988-2000 Chevrolet and GMC C/K 2500, 1988-2000 Chevrolet and GMC C/K 3500 and 6 more trucks in the fitment table, this BAKFlip FiberMax is a hard folding cover cut to that one bed. You get BAK's patented rail with a load-bearing flange, plus an internal water channel with drain hoses. It clamps to the bed rails with no drilling, using BAK's clamps plus a stake pocket clamp at the tailgate end. It folds to the two-thirds-open position or all the way to the cab, and the prop rods hold it there for driving. Coverage is BAK's 3-year limited warranty from the purchase date.
