A.Y. McDonald 74M3CT Frame and Cover Assembly Unit
The A.Y. McDonald 74M3CT (model 4174-030) is a frame and cover assembly designed for use with underground valve boxes and access structures in water distribution rough-in work. Installed at grade to provide a durable, walkable surface over buried shutoff valves, curb stops, or meter box openings, the frame and cover keeps the below-grade valve or meter access point protected from debris, soil intrusion, and surface traffic while allowing utility crews and plumbing contractors to quickly locate and access the valve for operation or service. As with other components in A.Y. McDonald's waterworks product line, the 74M3CT is built to be installed behind the finished surface and left largely unseen once backfilled or set into a roadway, sidewalk, or landscaped area, making it a functional rough-in component rather than a decorative fixture.
