Merritt underbody boxes are engineered from high-strength, corrosion-resistant aluminum and reinforced with lap-joint corner welds, providing greater structural integrity than standard butt-welded boxes. This rugged build ensures long service life even in harsh environments like construction sites, oil fields, and all-weather fleet operations.

Available in multiple sizes, depths, door options, and finishes, along with specialized lines like S-Series stackable boxes and cam-lock models, Merritt’s underbody boxes adapt to service bodies, trailers, and flatbeds of all types. The internal track system allows for add-ons such as shelves and lanyards, giving users the ability to customize their storage for improved organization and productivity.
