The Water-Tite Mini Round Dishwasher, Commercial Ice Maker, and Coffee Maker Outlet Box features a single-box design with a pre-installed valve and hammer arrester that saves contractors considerable installation time. Ideal for coffee kiosks, sinks, faucets, and toilet connections, this one-piece box has nails that are preloaded and reversible for a strong mount to either side of the stud bay. Molded-in side support brackets help ensure the box remains firmly affixed once installed. The included quarter-turn valve is made of durable and lead-free brass and complies with NSF 61-G requirements. The valve’s integrated hammer arrester absorbs sudden pressure changes to reduce stress on the plumbing system, providing continuous and maintenance-free protection against water hammer. This outlet box comes with a 6-1/8-inch-diameter faceplate that is able to accommodate up to 1-inch drywall.
