The Lomax hard tonneau cover provides complete protection for your truck bed and cargo. The tri-fold panels latch to the cover side rails at 10 points for enhanced security. These lightweight, impact-resistant aluminum panels can also be removed in seconds without tools for full bed access. The watertight cover opens with the pull of a cord at the tailgate, and it stores in the folded position at the cab with integrated storage clips and retractable straps.

Tri-Fold Design for Easy Bed Access

Fold panels for quick truck bed access

The cover has 3 panels that fold up for easy access to two-thirds of your bed.

Latch with release cable

To open the cover, simply pull one of the release cords on the driver's or passenger's side near the tailgate. Fold the rear and center panels on top of the front panel. There are built-in handles included to make this process easy.

Storage clips with retractable straps

The folded panels secure in place at the cab with integrated storage clips with retractable straps. Vinyl-coated spacers with rubber pads protect the folded panels by keeping them properly spaced. This ensures the cover will stay firmly in place while driving on a bumpy road, and limits metal-on-metal contact to reduce noise and vibration for a quieter ride.

Panels folded up for hauling flexibility

You still have plenty of rear window visibility with your tri-fold tonneau open. You can also haul long or tall items at the tailgate while still covering up cargo such as a toolbox that's stored closer to the bulkhead of the truck.

To access your full truck bed, lift up on the folded cover, and slide it away from the bulkhead of the truck. This will disengage the mounting hooks from the front catches on the side rails and allow you to completely remove the panels from the bed. Unlike many soft or hard covers, there are no hook-and-loop fasteners, snaps, or hardware to struggle with while operating the tonneau.

Sleek, Low-Profile Design

Low-profile design

The low-profile cover sits approximately 1/2" above your truck bed rails for an overall streamlined appearance. This aerodynamic design - when paired with a covered truck bed - also reduces wind noise and drag and helps to improve fuel economy. The tonneau is coated with a textured matte black finish that is stylish and improves the overall appearance of your truck.

Maximum Security

This hard cover is great for protecting your fifth wheel or gooseneck connection. It deters theft far better than soft covers that can be cut open with a knife. There are no exterior latches, so no one can access your truck bed.

Hooks and latches highlighted

The tri-fold panels automatically secure to the side rails at 10 points when closed. This helps to prevent would-be thieves from prying open the cover. These 10 security points consist of 2 hooks that slide into catches at the front of the truck bed, 4 additional hooks that fasten along the aluminum channels, and 4 latches that automatically engage to the side rails when the cover is lowered into the retainment brackets. Your cargo and truck bed are completely secured when the cover is closed and your tailgate is locked.

Heavy-Duty Construction

Closed cover protects cargo

The 3 heavy-duty panels are constructed of high-caliber aluminum that is 20 percent stronger than aluminum truck body parts. These impact-resistant panels can withstand hail and falling objects.

The tri-fold panels hold up to 400 lbs. of evenly distributed weight, yet they are light enough to be picked up by one or two people. The tonneau cover only weighs approximately 50 lbs. for a high strength-to-weight ratio.

Weathertight Protection

Weathertight rubber seal

The tonneau cover is designed to seal your bed from the elements to protect your cargo. To prevent water and dirt from entering the truck bed, the cover overlaps the bed rails with continuous watertight rubber seals along the entire length of the side rails. The vinyl-coated panel hinges are also waterproof.

Additionally, the cover has a barely visible arc to route water off the cover in the same way that a road has a slight grade to shed rain away. This water-shedding design - coupled with the other weathertight features - eliminates the need for drain tubes.

Simple, No-Drill Installation

The cover rails mount to the inside lips of the truck bed side rails. Simply place each rail against the lip and secure it in place with 4 Tight Bite clamps. Your stake pockets are not covered up, so they are still free for accessories.

Installing panels onto side rails

Angle the cover towards the bulkhead of the truck and slide it forward along the side rails until the mounting hooks engage the front catches on the side rails. Lower the cover into the retainment brackets, and unfold the cover. The cover will automatically latch to the side rails as you unfold it.

Safety straps with carabiner

For additional safety, attach the carabiner on the safety strap to the bracket located between the front and center panels.

Review from a similar Hard Folding Tonneau in Tonneau Covers

Very happy with this product. Works exactly as was shown on the video. No leaks and everything is secure......I've had many compliments as well. The only issue I had was when I received the the cover it had a large scratch. I never reported it as it is on the underside and the only time someone sees it is when I have the cover folded open. 579090

After a year I am still happy with the purchase of this cover. I would recommend it to everyone.
