The Dura-Flip is a hard folding tonneau cover made in Calgary, cut for the 6'9" box on 2020-2026 Chevrolet Silverado HD and GMC Sierra HD. Reinforced fibreglass top panels sit in a powder-coated aluminum frame and fold on the Weather-Flex hinge, so the cover holds its seal through snow and rain and still opens the whole box in seconds. It clamps to the bed rails with no rail kit to fit, and the weather seals are replaceable rather than bonded in - which is what keeps a cover serviceable through a Prairie winter instead of leaking after a few seasons.
