The Retrax IX retractable tonneau cover for 2007–2021 Toyota Tundra CrewMax (5.5 ft bed, without certain deck rail systems and storage boxes) is a flush-mounted roll-up cover made from aluminum slats linked by an elastomer hinge to help protect cargo from water and debris. The cover stows into a protective front canister via a quick-release handle while sealed rail bearings ensure smooth operation and adjustable latch stops add flexibility.
