The Extang Encore Tonno is a low profile, hard, tri-fold truck bed cover that offers unparalleled versatility. The Encore gives you easy access to your truck bed from both the front and rear panels! The Encore truck bed cover is self-positioning for quick and easy installation. Extang engineered rear latches lock the cover at the tailgate and supplemental tethers secure your cover to the side rails. The Encore features BOLT, one-key lock technology that allows you to lock Encore's front panel with your OE key. Extang-tuff 1-inch thick panels are made of automotive thermo-plastic (TPO) for unmatched impact resistance, superior UV protection and thermal stability. A textured, powder-coated frame and matte black rubber components combine to make the Extang Encore Tonno more stylish, easier to use, and more water resistant than any other hard folding truck bed cover! The Encore offers a near flush fit and matches the finish of OE bed rail caps incredibly well.
