Industrial rolling cabinets are designed and constructed with 18 gauge double walled steel construction. Two fixed and two swivel braked 5" rugged casters allow a load rating of 1400 lbs. Smooth action drawer slides are roll formed from a single piece of steel and are factory lubricated to resist binding under heavy loads. Feature “T” shaped Drawer fronts make the drawers 25% stronger and allow easy opening from any angle. Available with standard drawers plus a Drop-door bulk storage compartment. One key secures the entire cabinet with the automatic locking system – the tumbler lock automatically triggers the double lock bar securing all cabinet drawers once the pull down over the bulk storage compartment is locked. The exterior has an electro-deposited baked-on red enamel finish that is tough and easy to maintain.
