Heavy Duty Aluminum Truck Products

Semi-trucks and semi-trailers are designed to transport cargo efficiently. What they aren’t designed to do is carry the tools, extra batteries, and other gear necessary to keep them on the road safely. Whether you’re a truck owner or driver, carrying, having easy access to, and protecting these items from the elements or theft is critically important.

Merritt has long been relied upon for boxes and cab racks which provide adequate storage at affordable prices and with easy installation. This also makes us an ideal partner for parts managers looking for wide selection and availability in solutions for their clients.
