California Residents: Prop 65 Warning


Automatic Dual Locking System


Release both locks simultaneously by pulling the cord from either side. Heavy duty nylon latches provide 1/2 in. surface for solid positive engagement.

Automatic Ten Point Locking System


Unfolding each panel locks the cover automatically at ten points with heavy duty reinforced nylon components.

Tonneau Side Sealing


The water shedding design and waterproof hinges direct water away from the pickup box, no gutters or drains needed. The aluminum tri-fold tonneau overlaps the box rails with a continuous seal down the full length of the side rails, preventing elements from entering the pickup box.

Aluminum Channel


The LOMAX® Professional Series features additional aluminum channels under each panel. Extruded aluminum channels reinforce the panels to support up to 500 pounds of evenly dispersed weight, while weighing approximately 60 pounds for a high strength-to-weight ratio.

  • Storage Clip Latched
  • Storage Clip Unlatched


Retractable storage clips secure the truck bed cover and vinyl capped, rigid standoffs keep panels appropriately spaced in the folded position. No adjustments required.

Removing Hard Tonneau Cover


With tonneau cover open and storage clips secured, pull latches on front panel and disengage hooks by sliding cover back; lift to remove. Reinstall by sliding cover forward to engage hooks, then lower to automatically lock in retainment brackets.

" Great hard cover. Very easy install, and looks awesome. Seems durable enough, I'll review it again in a year or so. As of now I don't see any reason it won't last for many years to come. "

" Great product, love the looks and function of the Professional Series LOMAX hard cover. Keeps the weather out and flips open easily. I appreciate how it can be lifted off and slipped back on with ease. Awesome accessory for my 2018 GMC truck. "

" Solid Product that was super easy to install. Tonneau cover looks great. I ordered the urethane finish, which appears to be durable, but I did notice that the edges didn't receive very much urethane leaving some aluminum exposed. Not a huge deal. Tonneau cover was well packaged, yet still had a slight bend in the one corner of the cover that was able to be straightened out with a little pressure. Totally the shippers fault. "

Lomax Pro 5 star ratingBy Robert B. - TX

" I researched allot of covers out there. My criteria was QUALITY and LONGEVITY, this cover exceeded both. I've owned several covers before and they all had there downfalls. Aluminum is the only way to go, it installed problem free (25 minutes by my self) and can be removed easily. Also, I did not have any water in the bed after a wash. Save yourself time and buy it, yes it is higher priced but that's because of the quality. I have had mine for 8 months and am very satisfied. "
