Lomax 880 Heavy Duty Tonneau Cover – Premium Aluminum Tri-Fold
Our 880 heavy duty tonneau cover sets the standard for aluminum hard cover protection. Engineered with aerospace-grade aluminum panels and a reinforced tri-fold design, the 880 delivers unmatched security for your truck bed while maintaining the easy access you need every day.
We built the 880 to handle real-world demands—from construction sites to weekend adventures. The matte black powder-coated finish resists scratches and UV damage, while our proprietary hinge system supports up to 400 pounds of evenly distributed weight. Whether you’re securing tools, gear, or cargo, the 880 keeps everything protected from weather and theft.
Installation takes under 30 minutes with basic hand tools and our included clamp-on rail system. No drilling required. The cover folds completely out of the way for full bed access, and when closed, sits flush with your truck’s cab for a sleek, aerodynamic profile that improves fuel efficiency.
What makes the 880 engineered for strength

Aircraft-Grade Aluminum Construction
We manufacture the 880 heavy duty tonneau cover from the same aerospace-grade aluminum used in commercial aircraft components. Each panel undergoes a multi-stage powder coating process that creates a durable matte black finish resistant to chips, scratches, and corrosion.
The aluminum construction keeps the cover lightweight—under 60 pounds total—while delivering superior strength compared to vinyl or soft covers. This means you can operate the tri-fold mechanism easily with one hand, yet the closed cover provides hard-shell protection that discourages break-ins and shields cargo from impact damage.

Installation and Truck Bed Compatibility
The 880 installs on most full-size truck beds without drilling or permanent modifications to your vehicle. Our clamp-on rail system uses adjustable mounting brackets that grip your bed rails securely while allowing for removal if you ever need to take the cover off completely.
We include detailed installation instructions with every 880, along with all necessary hardware and an alignment tool that ensures perfect fitment. The rails adjust to accommodate beds from 5.5 feet to 8 feet in length, fitting popular models like Ford F-150, Chevy Silverado, Ram 1500, Toyota Tundra, and GMC Sierra.
Weather Protection and Sealing System
Every 880 heavy duty tonneau cover features our advanced weather sealing system with EPDM rubber gaskets along all panel edges and mounting points. These automotive-grade seals create a weathertight barrier that keeps rain, snow, road spray, and dust out of your truck bed.
The cover’s flush-mount design sits level with your cab, eliminating the gap where water typically pools on traditional covers. We’ve tested the 880 in commercial car wash conditions and extreme weather scenarios—from Arizona heat to Minnesota winters—to verify the seal integrity holds up year-round.

Common Questions About the 880 Heavy Duty Cover
The 880 supports up to 400 pounds of evenly distributed weight when fully closed and locked. This load capacity allows you to stack gear, coolers, or equipment on the closed cover surface during transport.
For optimal performance, distribute weight across all three panels rather than concentrating it on a single section. If you need to transport cargo exceeding 400 pounds, fold the cover completely open and secure items directly in your truck bed.
The 880 fits most full-size truck beds from 5.5 feet to 8 feet in length, including popular models like Ford F-150, Chevy Silverado, Ram 1500, Toyota Tundra, and GMC Sierra. Our adjustable rail system accommodates different bed widths and configurations.
Before ordering, measure your bed length from the inside of the bulkhead to the inside of the tailgate. Contact our customer service team with your truck’s year, make, model, and bed length to confirm exact fitment, especially if you have aftermarket bed liners or modifications.
No drilling is required to install the 880. Our clamp-on rail system uses adjustable mounting brackets that secure firmly to your truck’s bed rails without permanent modifications to your vehicle.
The installation process takes approximately 30 minutes with basic hand tools. We include all necessary hardware, detailed instructions, and an alignment tool to ensure proper fitment. The cover can be completely removed if needed, leaving no holes or damage to your truck bed.
The 880 features our advanced weather sealing system with EPDM rubber gaskets along all panel edges and mounting points. These automotive-grade seals create a weathertight barrier that prevents rain, snow, road spray, and dust from entering your truck bed.
We’ve tested the 880 in commercial car wash conditions and extreme weather from desert heat to winter freeze cycles. The flush-mount design eliminates water pooling areas, and the seals maintain their integrity across temperature extremes. For best results, clean the gaskets monthly and apply silicone seal conditioner in harsh climates.
Yes, the tri-fold design offers multiple opening configurations. You can fold just the rear panel for standard bed access with partial coverage, fold two panels for loading taller items like motorcycles or ATVs, or fold all three panels completely against the cab for maximum clearance.
Each panel locks in its folded position, so you can drive safely with the cover partially open. The smooth hinge mechanism operates easily with one hand, making it simple to adjust the configuration based on your cargo needs.
The 880 heavy duty tonneau cover includes our limited lifetime warranty on aluminum panels and hardware against defects in materials and workmanship. This warranty covers structural integrity, hinge mechanisms, and the powder-coated finish under normal use conditions.
Wear items like weather seals and cosmetic damage from accidents or improper installation are not covered. We also offer optional extended warranty plans that cover additional components and provide expedited replacement parts. Registration is required within 30 days of purchase to activate your warranty coverage.
Clean your 880 monthly with mild automotive soap and water using a soft cloth or sponge. Rinse thoroughly and dry with a microfiber towel to prevent water spots on the powder-coated finish.
Apply silicone seal conditioner to the EPDM rubber gaskets every 2-3 months to keep them pliable and maintain the weathertight seal. Avoid harsh chemicals, abrasive cleaners, or power washers that can damage the finish or seals. Lubricate the hinge pins annually with white lithium grease to ensure smooth operation.
