Designed, engineered, and manufactured with expert craftsmanship and automation processes, this cover delivers unmatched quality and consistency.

An advanced key-lock system further enhances theft resistance, keeping your valuable cargo safe and secure. Not only does the RealTruck FlushFit TS Manual resist thieves, but it also resists inclement weather. Proven in extremes from Alaska to Florida, this bed cover has been tested in the harshest conditions—from -40° to 180°F and zero to 95 percent humidity. Integrated into each side rail are dual drains, which deflect water out of the bed to keep cargo dry. | RealTruck FlushFit TS Manual Retractable Tonneau Cover w/ T-Slot Rails MRC30CH15A0
