Built For The Bed. Made To Work.
We’re Lomax — the American-designed hard tri-fold tonneau cover engineered to protect what rides behind you. Every panel we ship starts with a matte-black textured skin, a heavy-duty aluminum core, and a folding profile low enough to sit clean against your bed rails without spoiling the truck’s silhouette.
The Lomax story began in the trucking heartland with one stubborn idea: a hard folding tonneau cover shouldn’t rattle, shouldn’t fade, and shouldn’t quit on you three summers in. So we built the Professional Series, then refined it into the Stance — the same aircraft-grade aluminum bones, dialed in for haulers who care about the details.
From tri-fold cargo runs to locked-down overnight jobs, the Lomax Tonneau Cover lineup is engineered around one promise: quick access, real security, weather-tight seals, and a fit that looks like it rolled off the factory line. This is our official storefront — the entire collection, shipped straight from the source.

Shop NowHow We Engineer Every Lomax Cover
Three principles guide every hard folding tonneau cover we ship — from the Professional Series to the Stance, and every aluminum tri-fold in between.
Aluminum Core, Real Weather Skin
Every Lomax hard tri-fold is built around an aircraft-grade aluminum panel core. We top it with a UV-stable, matte-black textured skin that resists fading, chalking, and the fine cracking that ruins cheaper vinyl tonneau covers after a couple of summers.
Low-Profile, Truck-Specific
A tonneau cover should look like it left the factory on your truck. Our Professional Series and Stance covers sit low against the bed rails — no gaps, no bulge — with clamp geometry engineered for each supported truck platform so seals stay tight, corner to corner.
Folded In Seconds, Locked In A Click
Quick-release clamps let you fold the entire cover forward for full bed access, then lock it back down without tools. On our locking tri-fold, the tailgate keys the whole system — one click secures three panels of aluminum against the elements and prying hands.
What Truck Owners Say About Lomax
From daily drivers to job-site rigs, our owners run Lomax hard because it keeps working when the weather doesn’t.
“Installed the Professional Series myself in about twenty minutes. Zero rattles at highway speed and the seals actually stayed dry through a full week of Michigan snow. Best hard tri-fold I’ve owned.”
“Switched from a vinyl roll-up to the Lomax Stance and it’s a different truck now. Cleaner look, tighter fit, and I can fold the whole thing forward one-handed when I need to haul lumber.”
“I keep tools in the bed every day. The locking tri-fold plus the tailgate lock finally lets me stop unloading everything at night. Two years in — no fading, no leaks, no complaints.”

Lomax Tonneau Cover FAQ
The questions we get most from truck owners shopping the Lomax lineup.
What’s the difference between the Lomax Professional Series and the Stance?
Both are hard tri-fold tonneau covers built on the same aircraft-grade aluminum core. The Professional Series is our flagship — the original Lomax bed cover most owners know. The Stance is our refined build: a lower stance against the rails, sharpened clamp geometry, and a slightly cleaner integration for owners who want the tightest possible factory-fit look.
Are Lomax tonneau covers waterproof?
Our hard folding tonneau covers are engineered to be weather-tight, with sealed panel edges and full-length rail seals that keep out rain, snow, and highway spray under normal driving conditions. Because the panels are aluminum with a UV-stable skin, they don’t sag or stretch the way vinyl covers do, so the seal stays consistent over years of use.
Can I install a Lomax hard tri-fold myself?
Yes. Every Lomax hard tri-fold tonneau cover — Professional Series, Stance, or the classic hard tri-fold — is designed as a no-drill, clamp-on install. Most owners have the cover on the bed and locked down in 15 to 30 minutes with basic hand tools. Full step-by-step instructions ship with every cover.
How secure is the locking tri-fold tonneau cover?
Our locking tri-fold uses integrated clamps that engage when the tailgate is closed and locked. Because the front-most panel latches down behind the bulkhead and the rear panel is secured by the tailgate, opening the cover requires unlocking the truck first — turning your entire bed into a single lockable compartment.
