Completely Fit: This retractable truck bed cover is custom-designed for the 2009-2024 Dodge Ram 1500 with a 5'7" bed. It is not compatible with multifunction (split) tailgates or RamBox. Please measure your bed before choosing to ensure compatibility with your vehicle. Dual Lock Guard: The tailgate features two key locks to guard your cargo from theft while ensuring the cover stays securely closed, even during bumps or impacts. This level of security is not provided by most soft roll-up or folding covers. Smooth Manual Operation: The retractable design allows the cover to fully retract when not in use, making the truck bed space flexible. It can be opened or closed at any position, making it easy to load items of various sizes and shapes. Waterproof & Weatherproof: Made of durable aluminum panels with sealed edges and drainage tubes to direct rainwater away, this truck bed cover effectively keeps water and dirt out of the truck bed in all kinds of weather. Extra Cargo Space: Equipped with T-slot side rails, you can add racks or crossbars to transport more cargo. However, avoid leaving items on the truck bed cover for extended periods, as it may affect the cover’s performance and longevity.
