Every Tonno Pro folding tonneau cover is made with marine grade 24.5oz vinyl. This heavy duty cover is weather resistant, and hard to tear. The lightweight aluminum frame makes folding and moving the tonneau cover easy without sacrificing strength. The aluminum panels are finished with a black epoxy that resist corrosion and enhances durability. To haul larger cargo, the truck bed cover folds out of the way without needing to remove the entire assembly. The panels stay secured with included straps. When done hauling, the cover flips back closed in seconds! Each tonneau cover comes pre-assembled, which makes installation a breeze. And every Tonno Pro cover comes custom fit to your specific make and model. In minutes, you and your truck bed are covered! The EZ clamp system prevents the need to cut or drill into the truck. The clamps make installation and removal easy and pain free. Simply pop off the clamps to remove the cover in under 3 minutes. To secure the contents inside, the cover seals the truck bed when the tailgate is locked. Your Tonno Pro Tonneau Cover is covered by an industry leading 10 year vinyl **and lifetime frame warranty.
