NuAire's line of modular casework for the laboratory—including the ProGard NU-17 combination 7-drawer unit—is manufactured using stress-relieved, fully seam-welded, white corrosive-resistant polypropylene. All walls and floors of the modular casework are reinforced to maintain structural integrity and the outer cabinet shell, kick plate, and shelves are constructed from half-inch polypropylene. Each cabinet incorporates easy-to-clean shelves, handles, hinges, and screws, which are also made of 100% polypropylene. Doors are secured with Teflon coated magnetic catches. NuAire polypropylene casework is designed to accommodate modifications, additions, optional accessories, or customer-designed products that can be fabricated to meet the specific needs of a laboratory's applications.
