Keeping your tools or gear safe matters, especially when you leave your truck unattended. The Lomax Professional Series hard tonneau automatically secures at 10 points as you unfold it, locking tight when the tailgate is closed. With no exposed latches, it’s tough to pry open, so your cargo stays protected from theft and weather alike. The tri-fold panels hook into front catches and latch along the rails, sealing the bed into a solid, tamper-resistant compartment.
When you need to haul something tall or oversized, you don’t have to wrestle with complicated hardware. The cover folds up to open two-thirds of your bed, and when you need the full space, just lift it off—no tools required. Retractable straps and storage clips hold the folded panels steady while driving, and the built-in handles make folding easy from either side. It’s a simple setup that lets you switch between covered and open bed use in seconds.
This cover isn’t just for looks, though the black diamond mist finish definitely stands out. Each panel is made from high-strength aluminum—20 percent stronger than typical truck body panels—giving it impact resistance against hail or dropped gear. The panels can handle up to 400 lbs of evenly distributed weight while staying light enough to remove by hand. The UV-protected finish resists scratches and fading, keeping the cover looking sharp for years.
Rain, dust, or snow—your bed stays protected. Continuous rubber seals run the full length of the rails, and vinyl-coated hinges block moisture from seeping in. The cover has a slight arc that sheds water naturally, so you don’t need drain tubes or extra fittings. Even in heavy rain, it channels water away to keep cargo dry and the cover looking clean.
Sitting just about 1/2" above the bed rails, the Lomax Professional Series blends into the truck instead of sitting on top of it. The low-profile shape cuts down wind drag and road noise, helping with fuel efficiency while keeping the truck’s lines clean. It’s a tough, professional-grade cover that looks as solid as it performs.

We really like ths cover. Keeps the camping equipment in our truck secure and looks pretty flasy on our Laramie.
Relatively easy to install, looks great and seems to fit well. Etrailer delivered promptly, had great follow up and I will be ordering from them again! Great employees, I loved the self help videos done by the employees..
Great product! Easy install!
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.
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.
