LOMAX® Professional Series Cover
Heavy duty without the heavy weight, LOMAX® Professional Series is the right truck box cover for any job site. Emphasizing a one-person operation, this hard tri-fold cover is easy to install or remove. Sturdy black diamond urethane aluminum panels and a water-shedding design with strong, waterproof hinges shield your cargo and stop elements from entering the truck box. We added extra aluminum channels to each panel, enhancing strength to make the LOMAX® Professional Series Tonneau Cover even more durable with minimal increased weight. A ten point automatic locking system, flexible rubber seals and limited metal-on-metal contact reduce noise and road vibrations. LOMAX® Professional Series are hard truck box covers with long term reliability.
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.

Weathertight Seal
Water shedding design and waterproof hinges direct water away from the box without drains or gutters. The hard tri-fold cover overlaps the box rails with a continuous seal down the entire length of the side rails, preventing dirt, snow, rain and dust from entering the pickup bed.

Incorporated Storage Clips
Sleek, retractable storage clips hold truck bed cover in place and rigid standoffs with vinyl caps keep panels appropriately spaced in the folded position. No adjustments needed.

Strong, Yet Light in Weight
LOMAX™ Professional Series includes additional aluminum channels under each panel. The extruded aluminum channels support the panels to hold up to 500 pounds of evenly dispersed weight, while weighing approximately 60 pounds for an impressive strength-to-weight ratio.

Simple to Remove and Reinstall
With cover open and storage clips fastened, on front panel pull latches and disengage hooks by sliding cover back, then lift for removal. To reinstall, engage hooks by sliding the tonneau cover forward and place into retainment brackets. Cover locks automatically in place.

Cover is great. The professional is heavier than the regular. Wish the edges of the cover were painted to match the top. Edges are bare metal.

Terrific cover. Looks great, very strong and installation went well. It seems to be water proff. Very glad I went this direction.

Great cover! Well made, quality materials, decent instructions, and well packaged. Take a little time to get things level. Doesn't leak in heavy rain. Customer support is excellent as well.

Review by: John C. - TN,
Very nice cover. Only problem I had was it was not packaged very well for shipping. There were a few marks from loose parts in box.

Installed the Lomax professional tonneau cover on my 2023 Honda Ridgeline RTL-E SGP. Fit and finish looks great!. Seals seem to be good but the water channels on the bed wall towards the front seem to have an air gap. Hoping it is does not leak much. Side rails do reduce the opening of the in bed trunk hatch/door, but does not limit the usability much. Overall happy with the purchase!
