The recessed-style manifold wall cabinets feature a removable door-trim package and are adjustable to accommodate stainless-steel, brass or EP manifolds mounted in either a 2x4 or 2x6 stud wall. Mount an Uponor zone control module or wireless zoning base unit inside the cabinet for ease of wiring and protection from exposure or possible damage. Note: When recessing the cabinet in a wall, add 1/2 in to the height and width of the cabinet dimensions (shown in the part description) for easier installation. The adjustable door will cover the additional space surrounding the cabinet.
