The white 4-drawer side file cabinet is a built-in drawer interlocking system that prevents multiple drawers from being opened at once, thereby reducing the possibility of the cabinet tipping over. The center lock securely locks the sides of each drawer to ensure safety (two keys are provided). The adjustable outrigger level can keep the cabinet level in any environment. The ultra-deep drawer of the white 4-drawer side file cabinet can hold letters or legal size documents through the left and right hanging rails. Durable powder coating. The sides of curled or curled drawers have strength, rigidity and safety. ANSI/BIFMA grade. The all-steel full-width drawer handle has a double-wall reinforced drawer front panel for higher stability.
