      Leveled-Up Truck Bed Functionality. Level-up your Silverado truck’s functionality with the Extang Express Toolbox Tonneau Cover. This tonneau can be installed without removing your 18 to 20-inch size truck bed toolbox, providing your truck bed and its cargo with maximum all-weather protection. This tonneau cover maximizes the use of your truck bed’s setup, making it ideal for trucks that see a lot of field work. Additionally, this tonneau gives your truck a sleeker, more aerodynamic styling thanks to its 2-inch height when installed.

      Soft Roll-Up Style. The Extang Express Toolbox Tonneau uses a soft roll-up design employing a durable vinyl tarp that’s reinforced by removable aluminum support bows. These support bows give the tarp some stiffness that enables more efficient roll-up. The tarp is sealed fast against the mounting rails via heavy-duty hook and loop fabric strips that span the rails’ length. Also, a fast-release push-locking latch with a self-adjusting system keeps this tonneau cover securely closed, as well as pulled tight.

      Brawny Build. The Extang Express Toolbox Tonneau Cover’s mounting rails and support bows are made from a high-grade aluminum alloy that’s in a black anodized coating. This provides these components with superior strength, as well as excellent corrosion protection. Also, the tarp is made from industrial-grade vinyl that comes in a handsome black leather-grain finish that won’t fade or tear under normal use.

      No-Frills, No Mod Install. The Extang Express Toolbox Tonneau Cover installs directly on your truck bed rails and does not require any modifications. The mounting rails install using innovative clamps that mount recessed against your truck bed rails permitting maximum use of your truck bed’s cargo area. Also, this tonneau installs via an included Allen wrench for convenience.

      A Limited Lifetime Warranty Coverage. The Extang Express Toolbox Tonneau Cover is covered by a limited lifetime warranty against workmanship and material defects. Please visit the manufacturer’s website for more details.

      Application. The Extang Express Toolbox Tonneau Cover fits all 1999 to 2006 Chevrolet Silverado 1500 Fleetside models.
