Lomax Hard Tri-Fold Tonneau Cover – Removable Low-Profile Bed Protection
Our flagship Hard Tri-Fold Tonneau Cover combines aircraft-grade aluminum construction with a completely removable design that takes seconds to detach. The matte black powder-coated finish resists scratches and UV damage while maintaining a sleek, low-profile appearance that sits flush with your truck bed rails.
Engineered for drivers who need versatility, this cover folds in three sections for partial bed access or removes entirely without tools when you're hauling oversized cargo. We designed every hinge and latch to withstand extreme weather while keeping your gear secure and dry.
What makes our tonneau covers different
Aluminum Construction & Weather Protection
We build every Lomax tonneau cover with aircraft-grade aluminum panels that deliver professional-grade durability without the weight penalty of steel alternatives. The aluminum skin wraps a reinforced FRP composite core, creating a rigid structure that won’t warp or flex under snow loads or highway speeds.
Our matte black powder coat finish goes through a multi-stage curing process that bonds to the aluminum at a molecular level. This isn’t paint that chips off after a winter – it’s a permanent protective layer that resists road salt, UV rays, and the daily abuse of loading and unloading cargo. The sealed weather stripping system uses automotive-grade EPDM rubber that compresses evenly around the entire perimeter, keeping rain and dust out even during pressure washing.
Removable Design & Installation System
The removable feature is where our tonneau cover truly stands apart. When you need to haul plywood, a motorcycle, or anything taller than the folded cover allows, simply release the two integrated clamps and lift the entire assembly off your truck bed. The whole process takes about 10 seconds, and you can store the cover in your garage until you need it again.
Clamp-On Rail Installation
Our installation system uses heavy-duty clamps that attach to your existing bed rails without drilling holes or using adhesives. The clamps feature rubber-coated contact points that grip your rails firmly while protecting the factory finish. Most truck owners complete installation in under 30 minutes with just a socket wrench and the included hex key. We provide vehicle-specific installation instructions for over 140 popular truck models, ensuring a precise fit whether you drive a Ford, Chevy, RAM, Toyota, or GMC.
Security Features & Locking Mechanism
We engineered the dual-action latch system to provide genuine security, not just a deterrent. The primary latches integrate into the tailgate striker, so the cover cannot be opened unless your tailgate is unlocked first. When you lock your tailgate with your factory key or remote, you’re simultaneously securing the tonneau cover.
The latches use hardened steel strikers that resist prying and cutting attempts. We’ve tested these latches through 50,000 open-close cycles to ensure they maintain tension and alignment over years of daily use. The keyed cylinder at the tailgate provides backup security if you need to access the bed while keeping the tailgate locked, perfect for quick stops at gas stations or restaurants.

Common Questions About Lomax Hard Tonneau Covers
Yes, the entire cover lifts off in about 10 seconds without requiring any tools. Simply release the two integrated clamps and lift straight up. The cover weighs approximately 60 pounds, so most adults can handle removal solo, though having a second person makes storage easier. When you're ready to reinstall, just position the cover over your bed rails and re-engage the clamps.
Our clamp system accommodates most drop-in bed liners and spray-in coatings without modification. The clamps attach to your bed rails, not the bed floor, so liner thickness typically doesn't affect fitment. If you have an over-rail bed liner or bed cap, please contact our fitment team to verify compatibility, as these can alter rail dimensions.
The aluminum panels are engineered to support over 400 pounds of evenly distributed weight, easily handling heavy snow accumulation. The EPDM weather stripping remains flexible down to -40°F, maintaining a watertight seal in extreme cold. We recommend brushing off heavy, wet snow to prevent ice buildup around the hinges, but the cover itself won't crack or warp in freezing temperatures like some plastic alternatives can.
Absolutely. The tri-fold hinge system allows you to fold just the front panel independently, giving you access to approximately the first two feet of your bed. This is perfect for grabbing tools or gear stored near the cab without fully opening the cover. You can also fold the front two panels together while leaving the rear section closed, or fold all three against the cab for maximum access.
Every Lomax tonneau cover ships with all necessary clamps, weather stripping, installation hardware, and vehicle-specific instructions. You'll need a socket wrench or adjustable wrench and the included hex key – that's it. No drilling, no adhesives, no specialty tools required. Most installations take 20-30 minutes, and we provide online video guides for over 140 truck models if you want visual step-by-step help.
Yes, as long as your fifth-wheel or gooseneck hitch sits below the bed rails when not in use. Our tri-fold design allows you to fold the panels forward against the cab, providing clearance for most hitch systems. If you have a permanently raised hitch or bed-mounted toolbox, please verify clearance measurements with our customer service team to ensure compatibility.
The powder-coated aluminum surface cleans easily with automotive soap and water – just use a soft cloth or sponge to avoid scratching. Avoid harsh chemicals or abrasive cleaners. We recommend washing the cover when you wash your truck, and applying a UV protectant spray every 3-4 months to maintain the matte finish. The sealed hinges require no lubrication, and the weather stripping should be wiped clean occasionally to remove debris that could affect the seal.
