The Beta Tools C39MD Special Mobile Roller Cabinet has one centralized locking system that locks all 9 drawers. The drawers are all on ball bearing slides, and drawer fronts are all aluminum with the lift-to-open design. This unit comes with hinged bottom kick-plates which can be lowered to prevent items from rolling under the cabinet and then raised to access the casters/brake. The heavy-duty worktop is 60” long by 20.5” wide making it maneuverable in tight spaces. The C39MD has a static load capacity of 2,600 lbs.
