The Sandusky Lee Transport Series Mobile Storage Cabinet is constructed from heavy-gauge welded steel (20/22 gauge) for robust durability. The metal storage cabinet with wheels features a recessed locking handle with a 3-point locking system, ensuring secure mobile storage for use in offices, garages, classrooms, workshops, and more. This large-capacity cabinet includes four adjustable shelves, each supporting up to 230 lbs, and a 230 lb capacity raised floor shelf. Equipped with a heavy-duty 12 gauge caster base with four 6-inch swivel casters and smooth-rolling 5-inch wheels (two with side brakes), all mounted on a steel plate base and bolted through the cabinet bottom. A false bottom conceals the bolts, creating a raised floor shelf. The swivel wheels tuck under the base, allowing the cabinet to fit flush against walls when not in use. Its Greenguard Gold certified powder coat finish ensures low chemical emissions for improved air quality while providing a durable and attractive surface. The steel cabinet ships fully assembled. Please note, caster attachment is required.
