Lomax Hard Tri-Fold 110 Heavy Duty Aluminum Tonneau Cover
Our Lomax Hard Tri-Fold 110 represents the pinnacle of heavy duty aluminum tonneau cover engineering. We built this cover using aerospace-grade aluminum panels and a reinforced hinge system that handles the toughest conditions while maintaining a sleek, low-profile appearance on your truck bed.
The 110 series features our proprietary tri-fold design that gives you instant bed access without removing the entire cover. Whether you're hauling equipment for work or protecting gear on weekend adventures, this heavy duty construction delivers security and weather resistance that soft covers simply can't match.
We designed the 110 with integrated weather seals along every panel edge and a flush-mount configuration that sits just one inch above your bed rails. The result is a cover that looks factory-installed while providing maximum cargo protection and improved fuel efficiency through reduced wind drag.
What makes the 110 series unique

Heavy duty aluminum construction that lasts decades
We engineered the 110 using the same aluminum alloys found in commercial aircraft components. Each panel undergoes a multi-stage powder coating process that creates a durable finish resistant to UV damage, scratches, and harsh weather conditions.
The frame structure incorporates double-wall aluminum extrusions at stress points, reinforced with stainless steel hardware throughout. This construction method eliminates the warping and sagging issues common in lighter tonneau covers, ensuring your 110 maintains its tight seal and sleek appearance for years.

Tri-fold access system for maximum versatility
Quick-release folding mechanism
The 110 features our exclusive tri-fold hinge system that opens in sections for partial or full bed access. Lift the rear panel to access your tailgate area, fold two sections for mid-bed loading, or fold all three panels forward against the cab for unrestricted access to your entire truck bed.
Each hinge point uses sealed stainless steel components with integrated gas struts that hold panels in place at any position. You won’t need prop rods or additional supports—the cover stays exactly where you position it.
Weather protection and security features
We equipped the 110 with continuous EPDM rubber seals along every panel edge and perimeter. These automotive-grade seals create a weathertight barrier that keeps rain, snow, and dust out of your truck bed even during highway driving or extreme weather events.
The flush-mount installation eliminates gaps between the cover and bed rails, while our reinforced locking system secures at the tailgate with a keyed cylinder lock. The solid aluminum construction resists prying and cutting, offering security that soft or vinyl covers cannot provide.

Questions about the Lomax 110 tri-fold cover
The 110 heavy duty aluminum tonneau cover excels in extreme weather thanks to its aerospace-grade aluminum construction and continuous EPDM rubber seals. The powder-coated finish resists UV damage in intense sun, while the sealed hinge system operates smoothly in temperatures from -40°F to 140°F.
Internal drainage channels prevent water pooling during heavy rain or snow melt. The solid aluminum panels won't crack in freezing temperatures or warp in extreme heat like vinyl or fabric covers. We've tested the 110 in climates ranging from Arizona deserts to Canadian winters with consistently excellent performance.
Most truck owners install the 110 themselves in 20-30 minutes using only basic hand tools. Our no-drill clamp system requires no permanent modifications to your truck bed or rails.
We include detailed instructions with photos for each step, and our engineering ensures the cover aligns properly with minimal adjustment. The clamps tighten with a standard wrench or socket, and the cover's weight (typically 50-65 lbs depending on bed size) is manageable for one person, though having a helper makes positioning easier. Professional installation is available through our dealer network if you prefer assistance.
The 110 uses thicker gauge aluminum panels with reinforced internal ribbing that lighter covers lack. Our powder coating process involves multiple layers for superior durability, while budget covers often use single-coat finishes that fade and chip within a year or two.
The hinge system is the biggest difference—we use sealed stainless steel components with gas struts, whereas economy covers typically have exposed hinges that rust and fail. The 110's weather seals are automotive-grade EPDM rubber that remains flexible in extreme temperatures, not the generic foam strips found on cheaper alternatives. These engineering details add cost but deliver significantly longer service life and better performance.
Yes, the 110 accommodates most factory bed liners, spray-in liners, and drop-in bed protection systems. The clamp system adjusts to work with varying bed rail heights created by different liner types.
The cover is also compatible with most tonneau accessories including bed extenders, cargo dividers, and LED lighting kits. For aftermarket bed rail systems, stake pocket covers, or non-standard modifications, we recommend contacting our fitment team with your specific truck model and accessory list. We maintain compatibility data for over 300 truck configurations and can confirm fitment before you order.
The 110 is rated for up to 400 lbs of evenly distributed weight when fully closed and latched. This means you can safely stand on the cover during bed access or place equipment across the panels without damage.
However, we don't recommend the cover as a work platform for extended periods or concentrated point loads exceeding 100 lbs in one spot. The tri-fold design and hinge placement distribute weight effectively across the aluminum structure. For applications requiring higher load capacity, our Professional Series 300 offers reinforced construction rated to 600 lbs distributed weight.
We back the 110 heavy duty aluminum tonneau cover with a limited lifetime warranty on all aluminum panels and structural components against defects in materials and workmanship. This covers the panels, frame extrusions, and hinge assemblies for as long as you own the cover.
Moving parts including clamps, seals, and gas struts carry a five-year warranty from the date of purchase. The powder-coated finish is warranted against peeling, cracking, or excessive fading for three years under normal use and maintenance. Warranty coverage requires registration within 30 days of installation and adherence to our recommended maintenance schedule.
Absolutely. While the tri-fold design provides excellent access when folded forward, the quick-release clamp system allows complete cover removal in under two minutes without tools for maximum hauling capacity.
Simply release the spring-loaded clamps, lift the cover off your bed rails, and store it flat in your garage or against a wall. The cover weighs between 50-65 lbs depending on your truck bed size, making it manageable for one person to remove and reinstall. Many customers keep the cover off during specific projects and reinstall it when they need security and weather protection again.
