Extra long external mounting tabs allow an easy installation by nailing or screwing the boxes to wooden or steel concrete forms. Knockouts are sealed against box surfact to prevent concrete slurry and water from entering the box.
This octagon concrete box is used in poured concrete construction. It is installed on wooden or steel concrete forms. Once the forms are removed, the box and conduit is buried in concrete and the end is open to the room wall or ceiling, ready for wire pulling.
