All-Weather Cargo Protection: Weathertight Seals and Water-Shedding Design

Rain, dust, and road grime are no match for the Lomax Professional Series Hard Tonneau Cover. Continuous rubber seals run the full length of the rails, and the vinyl-coated panel hinges block moisture from seeping through. The cover’s slight arc helps water run off without the need for drain tubes, keeping your cargo dry even through storms or car washes.

Strong and Light: Aluminum Diamond Plate Construction

Daily work or weekend hauling demands a cover that can take hits without weighing you down. The three heavy-duty panels are made from impact-resistant aluminum that’s 20 percent stronger than typical truck body aluminum. They hold up to 400 lbs of evenly distributed weight, and at about 50 lbs total, the cover is still easy to lift off when you need the full bed. The black diamond mist finish resists scratches, UV damage, and everyday wear while giving the truck a clean, rugged look.

Full Bed Use When You Need It: Tri-Fold Design

When it’s time to haul tall or oversized gear, the tri-fold panels fold up fast for access to two-thirds of your bed. Integrated storage clips with retractable straps hold the folded cover steady against the cab, and rubber-padded spacers prevent metal-on-metal contact for a quieter ride. Need the entire bed open? Just lift the folded cover, slide it out of the front catches, and remove it completely without tools.

Secure and Simple: 10-Point Locking and Tailgate Latch System

Security is built in at every step. As each panel closes, ten locking points automatically engage along the side rails—two hooks at the front, four along the channels, and four latches that drop into place when lowered. With the tailgate locked, the bed is sealed and inaccessible from the outside. You can open it from either side using the quick-pull release cables at the tailgate.

Quick Setup: No-Drill Tight Bite Clamp Installation

Installing the Lomax Professional Series is straightforward: set the aluminum side rails inside the bed rails and secure them with eight Tight Bite clamps. There’s no drilling, and the stake pockets remain open for racks or other accessories. Once the rails are clamped, angle the cover forward to engage the hooks, unfold it, and the panels automatically latch into position. You’re ready to go—with a clean, low-profile cover that sits just ½" above the rails for a streamlined finish.
