California Residents: Prop 65 Warning



Automatic Dual Locking System


Release both locks simultaneously by pulling the cord from either side. Heavy duty nylon latches provide 1/2 in. surface for solid positive engagement.

Automatic Ten Point Locking System


Unfolding each panel locks the cover automatically at ten points with heavy duty reinforced nylon components.

Tonneau Side Sealing


The water-shedding design and waterproof hinges route water away from the bed without gutters or drains. The hard folding tonneau overlaps the bed rails with a continuous seal along the entire length of the side rails, preventing elements from entering the truck bed.

Aluminum Channel


Extruded aluminum channels support the panels to hold up to 400 pounds of evenly distributed weight, while weighing approximately 40-50 pounds for a high strength-to-weight ratio.

  • Storage Clip
  • Storage Clip


Sleek, retractable storage clips hold tonneau cover secure and rigid standoffs with rubber pads keep panels properly spaced in the folded position. No adjustments needed.

Tight Bite Clamps

Removing Hard Tonneau Cover


With LOMAX® Cover open and storage clips secured, pull tab on front panel and slide it back to disengage hooks, then lift to remove. Reinstall by sliding tonneau cover forward to engage hooks, then lower into retainment brackets. This folding truck bed cover automatically locks in place.

" I bought the Diamond Plate Finish tri-fold hard cover for my new Ford Maverick. I purchased the diamond plate finish hoping the interior of the bed wouldn't get as hot in the summer time. I was having trouble visualizing how the rails attached to the bed. I contacted ACI and they were very prompt in returning my call and very helpful. So far the cover is working fine. I'll know more in a year or 2. "

" Easy Install. Looks Good. Shortly after installation heavy rains were experienced for about 2 days. Minimal leakage noted on front corner (Passenger Side). Just a Drip. I also purchased a bottle of ACI Bed Cover Cleaner/Protectant. It was easy to apply and gave the cover a clean satiny finish. No glare or reflection "
