Sonic S11 Toolboxes maximize strength and rigidity by stamping the whole box from one piece of steel, then the sides are folded up and welded. This efficient design makes it stronger and the process is more efficient. The Sonic Anti-Tilt mitigates the risk of tipping, when one drawer is opened, all the other drawers are automatically locked, ensuring that most of the weight is still centered over the large 5" casters. Two of the casters swivel and include locks while the other two are stationary. The S11 toolbox comes in powder-coated Blue.
