"Designed for service pickup trucks with boxes, the Elevate Outdoor Steel Universal Service Truck Rack holds equipment and materials up to 1,000 lbs. when the cargo length is prohibitive for the cabin or boxes. Manufactured from durable, power-coated steel, it is height adjustable from 21” to 30” to accommodate varied box heights. Four integrated tie-down cleats make it easy to secure your load, and 5"" guard rails keep horizontal cargo from slipping off the side. The rack can be mounted on the top of the boxes, on front or rear panels, or other location depending on the truck’s box setup."
