Masonry Electrical Box · 4 Gang · Deep 3-1/2 in (89 mm) Welded Steel · Vista MBD4K
SKU: MBD4K
4-gang deep masonry electrical box in welded galvanized steel for conduit installations in block, brick, and masonry walls. The 3-1/2 in (89 mm) depth provides added wiring space compared with shallow masonry boxes, which is typically helpful where multiple device conductors and splices need more box volume; actual fill must be verified to code.
What this product is for
This 4-gang deep masonry box is used to mount wiring devices in masonry, block, or brick wall construction where a metal box and conduit entry are required. It is a welded steel box intended for commercial and institutional rough-in as well as other conduit-based installations.
Use for
Use for switches, receptacles, and multi-device layouts in masonry walls where a deeper box helps provide more conductor space. Commonly used where conduit enters from multiple sides and where electricians need a rigid metallic box with concentric knockouts.
Avoid for
Avoid using this box where a shallow wall cavity or non-masonry framing method calls for a different box style, or where a non-metallic box is specified. Do not assume box fill suitability without checking conductor count, device allowance, fittings, and local code requirements.
Best for
Best for 4-device masonry rough-in where deeper capacity is preferred over a shallow masonry box. A practical trade-level rule of thumb is that deeper boxes are commonly chosen when device count, conductor count, or conduit entries make wiring space tighter. Actual performance depends on installation conditions, conductor size, fittings, and local electrical code.
Installed in
Typically installed in concrete block, brick, and other masonry wall assemblies in commercial, institutional, and mixed-use projects. Suitable for conduit-based branch circuit installations.
Why this product exists
This product exists to provide a fixed 4-gang metallic box format for masonry construction with deeper internal space than shallow versions. The welded steel body and galvanized finish support standard jobsite use where strength, conduit compatibility, and multiple knockout options matter.
Compared with similar products
Compared with a shallow 4-gang masonry box, this deep version offers more internal volume and is typically the better choice when wiring density is higher. Compared with adjustable or open-back masonry boxes, this style is a conventional fixed-depth welded box for standard conduit rough-in.
