How to Measure Truck Bed



The LOMAX™ Professional Series boasts maximum protection with an innovative low profile design. This diamond plate, hard tonneau cover emphasizes a weathertight seal, easy installation and simple one-person operation. The aluminum panels with a water shedding design and reinforced waterproof hinges prevent elements from entering the truck bed. Added extruded aluminum channels under each panel increase strength, making the LOMAX™ Professional Series stronger with minimum additional weight. For a quiet ride, limited metal-on-metal, water resistant hinges and flexible rubber seals combine to reduce noise and vibration. Redefining rugged, the LOMAX™ Professional Series is committed to quality and durability.

Weather Tight Tonneau Seal

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

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 Tonneau Cover

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 Tonneau Removal

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.

Tight Bite Clamps

TIGHT BITE™ Clamps

Installs in minutes without the need to drill into your truck box. Specifically cut 'teeth' maintain superior grip and exceptional strength.

If you're looking for a great low profile truck box cover that looks awesome, this is it. When needed it can be removed very easily as compared to a retractable that even when rolled away takes up bed space. Fit perfect on my 2017 Ford F-150 with 5.5ft bed.

The diamond plated tri-fold cover was easy to install and looks great.

This hard tri-fold tonneau cover was everything as advertised. Installation was a breeze and since installed, we have had rain and everything in the truck box has stayed dry. I have already recommended it to my friends.

LOMAX™ Professional Series Customer Review Package arrived quickly and in great shape. The parts were packaged well, so that all the parts were in perfect condition. Installation was relatively easy, although the clamps were a bit fiddly. Having a helper would have made the installation easier, but it wasn't too bad to do it by myself. The cover looks great and fits on my Chev. Silverado CC SB Z71 perfectly. It isn't perfectly water-tight against rain, but very close! I like being able to open close the tailgate without worrying about the position of the rear of the cover. I also like the ability to remove the cover completely with minimal effort.
