Upgrade your heavy-duty Chevy or GMC with the Access LOMAX® Tri-Fold Tonneau Cover – Black Urethane Finish – B3020099, engineered for 2020, 2021, 2022, 2023, 2024, and 2025 Chevrolet Silverado 2500 / 3500 and GMC Sierra 2500 / 3500 trucks with the 6 ft 8 in standard bed. This hard folding truck bed cover offers a premium blend of durability, weather protection, and sleek, low-profile styling.

Exact Fit for Silverado HD & Sierra HD

Designed to match the exact bed dimensions of Silverado and Sierra HD models, the LOMAX® Tri-Fold mounts securely with a clamp-on, no-drill design. Whether you own a 2020 Silverado 2500 WT, a 2023 Sierra 3500 Denali, or a 2025 Silverado 3500 High Country, this tonneau cover delivers a perfect fit and high-end look.

Premium Black Urethane Finish

The black urethane coating provides a deep, refined appearance while adding an extra layer of scratch, UV, and weather resistance. It keeps your truck bed cover looking sharp for years, even under tough working conditions and constant outdoor exposure.

Low-Profile Hard Folding Design

The LOMAX® sits just 1/2 inch above the bed rails for a flush, aerodynamic appearance. Its tri-fold panel system allows you to open it partially or fully in seconds, giving you quick and versatile access to your truck bed.

All-Weather Truck Bed Protection

With water-shedding channels and reinforced perimeter seals, this tonneau cover is built to handle heavy rain, snow, dust, and debris. The corrosion-resistant aluminum panels ensure strength without adding unnecessary weight, making it ideal for daily driving or demanding job sites.

Secure Tailgate-Locking System

The LOMAX® Tri-Fold locks automatically with the tailgate—when your tailgate is locked, so is your cover. No extra keys or complex locking mechanisms are needed, keeping your gear secure with minimal effort.

Full-Bed Access On Demand

Fold the panels forward for partial or full-bed access. Built-in prop rods let you secure the cover upright while driving with oversized loads, making it perfect for hauling tall equipment, materials, or recreational gear.

Fast, No-Drill Installation

The clamp-on, bolt-on mounting hardware makes installation simple and quick—most truck owners can install the LOMAX® in under an hour using basic tools. Removal is just as easy when you need a completely open bed.
