Secure Cargo in Any Weather: Weathertight Aluminum Panels

Rain, dust, and road grime can quickly ruin what’s in your truck bed. The Lomax Professional Series Hard Tonneau Cover seals tight against the elements with continuous rubber seals and waterproof, vinyl-coated panel hinges. The panels sit in a slight arc to help water run off instead of pooling, so you don’t need drain tubes. Whether it’s a thunderstorm or a wash bay, your cargo stays dry and protected.

Everyday Access Made Easy: Tri-Fold Design

Getting to your gear shouldn’t mean removing the whole cover. With the tri-fold design, you can open two-thirds of the bed by simply pulling the release cords at the tailgate. The panels fold neatly toward the cab and lock in place with retractable straps and clips. When you need the full bed, the lightweight aluminum panels lift off without tools. It’s quick, simple, and keeps you ready for whatever you’re hauling next.

Strength You Can Count On: Heavy-Duty Aluminum Build

This cover doesn’t just look tough—it is. The three impact-resistant aluminum panels are 20 percent stronger than aluminum truck body parts and support up to 500 lbs of evenly distributed weight. Even with that strength, the whole cover weighs only about 50 lbs, giving it an excellent strength-to-weight ratio. The black diamond mist finish resists scratches, UV damage, and impacts for long-term durability.

Tight Security Without the Hassle: 10-Point Locking System

Leaving tools or gear unattended is a lot less stressful with this cover in place. The panels automatically secure to the side rails at 10 points as they close—using a combination of hooks and latches for serious tamper resistance. There are no exterior latches, so when paired with a locked tailgate, the bed stays completely secure.

Clean Look, Simple Install: Low-Profile, No-Drill Mounting

The Lomax sits just?½ inch above the bed rails for a streamlined, low-profile look that reduces wind drag and can even help fuel economy. Installation is straightforward with 8 Tight Bite clamps—no drilling needed. The rails mount inside the bed, keeping stake pockets open for racks or other accessories. It’s a clean, functional setup that looks built-in, not bolted on.
