Lomax Hard Tri-Fold Tonneau Cover 110 – Premium Rigid Bed Protection
Our Lomax 110 hard tri-fold tonneau cover brings rigid aluminum panel construction to your truck bed without sacrificing daily convenience. This premium cover folds in three sections, giving you full bed access when you need it while maintaining a sleek, low-profile appearance that complements any truck style.
We engineered the 110 with aircraft-grade aluminum panels that resist dents, UV damage, and extreme weather conditions. The tri-fold design lets you access your cargo from the cab or tailgate, and the entire cover folds completely open against the cab for full bed use. Installation takes under an hour with our no-drill clamp system that works with most factory bed rails.
Whether you're protecting tools, gear, or groceries, the 110 delivers security and weather resistance that soft covers simply can't match. The integrated drainage channels and heavy-duty weather seals keep moisture out, while the matte black finish resists scratches and maintains its appearance season after season.
What makes the 110 stand out
Aluminum Panel Construction & Durability
We build the Lomax 110 with aircraft-grade aluminum panels that deliver superior strength without the weight penalty of steel covers. Each panel undergoes a precision powder-coating process that creates a durable matte black finish resistant to chips, scratches, and corrosion.
The aluminum construction means the 110 won’t crack in freezing temperatures or warp in desert heat. We’ve tested these panels in temperature extremes from -40°F to 140°F, and the material maintains its structural integrity without becoming brittle or losing shape. The powder-coat finish also resists UV rays, so your cover won’t fade or chalk after years of sun exposure.
Tri-Fold Access & Operation
The 110’s three-panel design gives you flexibility that single-piece lids can’t match. Need to haul something tall at the front of the bed? Fold back just the first panel. Loading from the tailgate? Open the rear two panels. When you need full bed access, all three panels fold completely against the cab in seconds.
We designed the hinge system with gas struts that assist lifting, so opening the 110 requires minimal effort. The panels lock in the folded position, staying secure while you drive with the cover open. Quick-release latches on each panel let you operate the cover with one hand, and the pull handles are positioned for easy reach from either side of the bed.
Weather Protection & Sealing System
Our 110 tonneau cover uses a multi-point weather seal system that keeps rain, snow, and dust out of your truck bed. We install EPDM rubber seals along all four edges of each panel, creating overlapping barriers that block moisture entry even in driving rain or when snow accumulates on top.
Integrated drainage channels run along the side rails, directing any water that does penetrate toward the tailgate and away from your cargo. The channels prevent pooling that could seep through panel joints. We’ve refined this drainage design through years of real-world testing in Pacific Northwest winters and Midwest thunderstorms.

Common Questions About the Lomax 110 Tonneau Cover
Yes, the 110 works with spray-in bed liners, drop-in liners, and most bed mats. Our clamp system adjusts to accommodate the additional thickness that liners add to the bed rails. The clamps sit above the liner surface and still create a secure, weathertight seal. If you have an exceptionally thick custom liner over 0.5 inches, you may need our clamp spacer kit for optimal fit.
Absolutely. We designed the quick-release latches and gas-strut-assisted panels so you can open any section of the 110 with one hand. The pull handles are positioned for easy reach from either side of the bed, and the latches release with a simple squeeze. The gas struts do most of the lifting work, so even the full three-panel opening is manageable single-handed.
The 110 offers superior security, weather protection, and durability compared to soft covers. The rigid aluminum panels resist cutting and prying, while soft vinyl can be sliced through. Our weather seals and drainage system keep moisture out more effectively than fabric covers, especially in heavy rain or snow. The trade-off is that hard tri-folds like the 110 cost more upfront, but they last significantly longer and provide better cargo protection.
Soft covers are lighter and typically easier to remove completely, but the 110's clamp system allows full removal in minutes if needed. For most truck owners who want long-term protection and security, the rigid construction justifies the investment.
We back the Lomax 110 with a comprehensive warranty that covers defects in materials and workmanship. The aluminum panels carry a lifetime warranty against cracking, warping, or structural failure. Hardware components including hinges, latches, and clamps are covered for three years. Weather seals are warranted for two years against premature wear or deterioration.
Our warranty doesn't cover damage from accidents, improper installation, or modifications. We stand behind the quality of the 110 and work directly with customers to resolve any issues that arise during normal use.
Yes, the Lomax 110 works with most cab-mounted roof rack systems and over-cab ladder racks. The cover's low profile and fold-forward design don't interfere with rack installation. When you need to access roof-mounted cargo, you can stand on the closed 110 panels safely thanks to the 400-pound load capacity.
If you're installing bed-mounted crossbars or a truck tent system, you'll need to fold the 110 panels forward or remove them temporarily. The no-drill clamp system makes removal and reinstallation straightforward when you need maximum bed access for specific hauling situations.
Maintenance is minimal. Wash the 110 with mild soap and water whenever you wash your truck, and dry it with a soft cloth to prevent water spots. We recommend applying a spray protectant designed for powder-coated surfaces every few months to maintain the matte finish.
Lubricate the hinges and latches twice a year with silicone spray to keep them operating smoothly. Check the weather seals periodically and clean any dirt or debris from the seal channels. Our maintenance kit includes all the products you need for proper care. With basic maintenance, the 110 will maintain its appearance and function for many years.
Most customers report a modest improvement in fuel economy after installing the 110, especially during highway driving. The low-profile design reduces aerodynamic drag compared to driving with an open bed. While individual results vary based on driving habits and conditions, the streamlined cover typically improves efficiency by reducing turbulence in the bed area.
The difference is most noticeable at speeds above 55 mph. City driving may not show significant fuel savings, but the cumulative effect over time can offset a portion of the cover's cost through reduced fuel consumption.
