Effective air distribution in buildings
The MH Tuffbox is a seamless register box that distributes air in buildings without leaking. The box connects the air diffuser to ductwork with a stepped collar that accommodates three duct diameters, reducing the number of parts needed. The box, which is one-piece molded polymer, is airtight and condensation-resistant, and improves indoor air quality while saving energy. Choose 6-by-6-, 8-by-8-, or 10-by-10-inch sizes with three different collar diameters for each.
