Masonry Electrical Box · 1-Gang · 3-1/2 in Deep · Steel Masonry Box · Ortech MBD1K
SKU: MBD1K
1-gang deep masonry electrical box for switches, receptacles, and device installations in brick, block, or concrete walls. Source-supported listings indicate a 3-1/2 in (89 mm) depth and approximately 21 cu. in. capacity, giving more wiring space than shallow masonry boxes for typical device and conductor fill.

What this product is for
This steel masonry box is used to mount a single wiring device in masonry, brick, block, or concrete wall construction. It is intended for flush device installation where a metal box is required behind the finished wall surface.
Use for
Use for single-gang switches, receptacles, and similar devices in masonry wall assemblies. The 3-1/2 in (89 mm) deep format is commonly selected when extra conductor space is needed compared with shallow masonry boxes.
Avoid for
Avoid using this box where a non-metallic box is specified, where wall depth is too limited for a 3-1/2 in (89 mm) box, or where a multi-gang arrangement is required unless the project design specifically allows it.
Best for
Best for electricians roughing in device locations in block or concrete walls and needing a standard 1-gang steel box with deeper wiring space. It is also a practical choice where device depth or conductor count makes shallow boxes less suitable.
Installed in
Typically installed in residential, commercial, and institutional masonry walls, including brick veneer, concrete block, and poured concrete applications, subject to local code and installation method.
Why this product exists
Masonry walls do not use standard stud-wall device boxes in the same way as framed construction. A dedicated masonry box provides a flush mounting point for the device while giving the installer a steel enclosure sized for conduit entries and box-fill needs.
Compared with similar products
Compared with shallow masonry boxes, a 3-1/2 in (89 mm) deep box typically gives more room for splices, feed-through conductors, and deeper devices. Actual box-fill suitability depends on conductor size, device type, grounding, and local electrical code.
