This deluxe cabinet features a heavy-gauge steel, 16-gauge door frame for rugged storage and use. Louvered back panel provides cabinet ventilation by allowing air circulation. Four of the five shelves adjust in 2" increments without tools. Built-in shelf support tabs secure shelves tightly to cabinet without clips or added parts, adding rigidity and preventing small items from falling over edge or rear of shelf. Each door incorporates an extra-wide reinforcement welded for added strength and stability. Four knuckle-hinges offer secure and smooth operation. Two brushed chrome handles, with one that locks both doors, make door opening and closing easy. With three-point locking mechanism, you can simply turn the handle, and doors lock at three points for maximum security. Nylon guides help make operation quiet. Raised base uses a box construction for added overall stiffness and keeps materials out of harm's way from cleaning liquids. Two adjustable levelers compensate for uneven floors.
