The Gator SRX Roll-Up Tonneau Cover features a classic soft roll-up design consisting of a marine-grade vinyl tarp and lightweight yet dependable aluminum side rails and bows. While not impervious to sharp blades, this cover is an effective theft deterrent, especially with a locked tailgate! The Gator SRX doesn't just guard against would-be thieves, but also moisture intrusion! The sides of the cover seal against the side rails using automotive-grade hook-and-loop fasteners, while bulkhead and perimeter seals prevent moisture from creeping into the bed and tarnishing your valuables | Ram Truck 1500 Gator SRX Roll-Up Tonneau Cover
