Stanley Proto's line of mobile tool chests for heavy industrial use includes three units that are compact enough to move around a crowded work area, yet strong enough to carry a full collection of tools. Drawer capacity is 400 pounds per drawer and weight capacity per wheel is 800 pounds. Thick, 16-gauge powder-coated steel construction minimizes the chance damage, even when moving the cabinets around fully loaded. A tubular lock system secures all drawers with a single key. A safety latch on each drawer keeps the drawer from opening during transport. The line includes 45-inch and 30-inch lengths, all with 21-inch depth. Internal drawer dividers are supplied and a vinyl top is standard. For more information visit www.stanleyproto.com or call (800) 800-TOOL.
