The TACTIK Low Profile Hard Tri-Fold Tonneau Cover is exclusively designed for truck beds to provide a sleek, stylish look. This premium tonneau is UV and cold-resistant for years of trouble-free use. Durable material helps protect any bed cargo from moisture, dirt, or any other elements your truck may face. Tonneau mounts to the truck bed rail using a unique clamping system, theft protection rail, and latch design. A simple release mechanism can be operated with one finger. The hard panel is scratch resistant and provides maximum theft protection for all bed cargo as the cover will automatically lock when the last fold closes and you lock the tailgate. Hard panels are rated up to 500 lbs of evenly distributed weight. Tonneau does require assembly, but no additional tools or drilling is needed.
