The Tonno Pro TonnoFold Tri-Folding Tonneau Cover has become the fastest growing cover in its class. And for good reason. The hinged together sections make it easy to fold it into a more company unit. You can remove it in seconds when you have oversized cargo or simply fold it forward to lock in place for smaller loads. Our Tri-Fold tonneau cover comes completely assembled – NO DRILLING. This makes installation of your truck topper a snap. Our Tonno Pro Tri-Fold cover is unmatched in quality. It features tear-resistant double sided vinyl, and a 6063 grade powder coated frame this cover – both are covered by the industry's best warranty. Not only does the Tonno Pro tri-fold provide you the protection and functionality you need, but it does it with our Low Profile Styling that will look great on any truck. Plus it can save you gas and keep your truck looking great for years to come.
