Features to know about

Secure Cargo in Any Weather: Heavy-Duty Aluminum Panels

When you’re hauling gear, tools, or groceries, you want to know everything in your bed stays protected from theft and weather. The Lomax Professional Series uses impact-resistant aluminum panels that are 20 percent stronger than aluminum truck body parts. They latch automatically at 10 points along the side rails for maximum security when the tailgate is locked. Continuous rubber seals and vinyl-coated panel hinges keep out water and dust, while the slight arc in the cover sheds rain without needing drain tubes.

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

You don’t have to choose between cargo protection and hauling space. The tri-fold design lets you open two-thirds of your bed by simply pulling one of the release cords near the tailgate. Built-in handles make folding easy, and integrated storage clips with retractable straps keep folded panels secured while you drive. When you need full bed access, lift the folded cover away from the bulkhead—no tools required.

Clean, Low-Profile Appearance: 1/2" Above Bed Rails

A tonneau cover should look like it belongs on your truck, not sit up awkwardly above it. This one sits just about 1/2 inch above the bed rails for a streamlined, low-profile look that also reduces wind drag and helps with fuel economy. The black diamond mist finish is scratch resistant, UV protected, and absorbs impacts while keeping a bold, polished appearance through years of use.

Built to Handle Real Work: 500-lb Weight Capacity

For those who actually use their trucks, durability is key. This cover supports up to 500 lbs of evenly distributed weight while weighing only about 50 lbs itself. Extruded aluminum channels reinforce each panel for strength without adding bulk. It’s tough enough to withstand hail or falling debris but still light enough for one or two people to remove easily when needed.

Simple Setup and Rack-Friendly Fit: No-Drill Installation

Installing this cover doesn’t require drilling or complicated tools. The side rails clamp securely with eight Tight Bite clamps that attach to the inside lips of your bed rails. Stake pockets remain open for racks or other gear, so you can keep hauling ladders, kayaks, or overland equipment without giving up bed protection.

This is the 2nd time I have bought my tonneau cover and side rails for my truck and once again the products are top notch and look amazing on my truck. My first purchase was for a Nissan Frontier Pro4X. This time it was for a GMC Sierra 1500 crew cab. Thank you too E-Trailer for helping make my truck awesome. I highly recommend E-Trailer for any after market upgrades.

The product is excellent! The only problem I had is that the box it was shipped in was very damaged, one side torn open. There was no damage to the product and all parts were there but the shipper did a very poor job patching up the box.

Awesome! Keeps things in the bed dry and safe. It’s sturdy, quiet and efficient to open and close. If I have something taller than the bed walls, it folds up easily into a compact size so it can be easily stored in the bed, and put back in when cargo is removed

  • Does the Lomax Hard Tonneau Cover Fit With MultiPro Tailgate On 2020 GMC Sierra 2500
    The Lomax Hard Tonneau Cover part # AB1020099 for the 2020 GMC Sierra 2500 6-3/4 ft bed is not affected by the MultiPro Tailgate and is still a perfect fit. The Lomax Cover is a great option for the Sierra because of it's nice low profile aluminum construction. The panels fasten to the side rails at 10 different fasten points for extra security. Please keep in mind this option does over the stake pockets. I recommend to use the Lomax Professional Series Hard Tonneau Cover - Folding...
