The Genesis Seal and Peel Tonneau Cover features a unique snapless closure system that opens and closes much quicker and easier than traditional snap or Hook & Loop covers. This superbly engineered cover and rail system provides a perfect, no-adjustment fit - even in extreme climates. Pre-marked rails and heavy duty clamps assure an easy, no-drill installation in under 20 minutes. Integrated rear tailgate seal won't get knocked off like adhesive seals.
