Description

The Access G4020099 LOMAX Stance Hard Tri-Fold Tonneau Cover is a robust and lightweight truck bed cover designed for specific Chevrolet Silverado and GMC Sierra heavy-duty models. It features extruded aluminum panels with a durable, textured urethane finish, similar to a spray-in bedliner, allowing it to support up to 400 lbs of evenly distributed weight. Its ultra-low-profile design means it sits just ½-inch above the bed rails, offering a sleek and subtle appearance. Key features include the RIGIDLINK Locking System, which secures the cover at a 90-degree angle to allow for full bed usage without obstructing the rear window. An Automatic Dual Locking System enables simultaneous release of both locks from either side of the tailgate with a pull of a cord. The cover also incorporates a weathertight seal with waterproof hinges and a continuous seal along the side rails to effectively shed water and keep the truck bed dry. Installation is straightforward and clamp-on, requiring no drilling into the truck bed, and utilizes a "Tight Bite Clamp" for a secure grip. Molded storage brackets, retractable bungees, and rubber pads ensure the panels are properly spaced and secured when folded, with no adjustments necessary. Each panel also features an Automatic Ten Point Locking mechanism for added security without the need for a key. This tonneau cover is proudly manufactured in the USA and comes with a limited 3-year warranty. It is compatible with or without a Multi Tailgate but will not work with bedside storage boxes.
