This tonneau cover uses an elegant-looking vinyl tarp that’s secured using classic fiberglass-reinforced snap buttons. This no-frills design is easy to use and weather-proof, keeping your valuable cargo safe from the elements.
Soft Roll-Up Style. The Extang Blackmax Snap Tonneau Cover utilizes a soft roll-up style. This tonneau’s posh-looking vinyl tarp adds streamlined appeal to your truck while completely protecting your truck bed. This cover secures using fiberglass-reinforced snap buttons that can be adjusted together with its spring bows. This adjustability allows you to either get a more streamlined look or increase its aerodynamic properties. This bed cover’s mounting rails also employs a quick-release tail section enabling you to fully access your truck bed. Lastly, this tonneau allows you to tweak the tarp’s tightness depending on how hot it is.
Rugged Construction. The Extang Blackmax Snap Tonneau Cover’s mounting rails and spring bows are made from high-grade aluminum for strength minus the weight. Both the rails and spring bows are black-anodized providing the tonneau with a sleek look when the tarp is rolled up. The tarp is manufactured from tough vinyl and comes with a black faux leather-grain look. This tarp rolls-up easily and is secured via built-in straps in the open position.
Trouble-Free No-Mod Install Procedure. Installing the Extang Blackmax Snap Tonneau Cover is a trouble-free procedure. This tonneau installs on your Sierra’s bed rail using a convenient double clamping system. No modifications to your truck are necessary, and standard hand tools are all you need for installation.
