Masonry Box · 3-Gang · 3-1/2 in Deep 63 cu in Steel · Hubbell TradeSelect MBD3K
What this product is for
This 3-gang steel masonry box is used for the flush installation of switches, receptacles, and similar wiring devices in masonry construction. It is intended for conduit wiring systems and provides a rigid metal enclosure for commercial, institutional, and residential masonry wall applications.
Use for
Use for multi-device installations in block, brick, or concrete walls where a 3-gang box is required. Suitable where a 3-1/2 in (89 mm) deep box and multiple combination knockouts help with conduit entry and device spacing.
Avoid for
Avoid using this box where a gangable box is required, where non-metallic cable entry is needed instead of conduit, or where wall conditions call for an adjustable or old-work style box.
Best for
Best for new masonry construction requiring a fixed-depth, welded steel box for three devices. Also useful where electricians want a standard masonry box format with CSA certification and common 1/2 in and 3/4 in combination knockouts.
Installed in
Typically installed in masonry walls in commercial corridors, utility spaces, apartment buildings, schools, and other projects using conduit systems. Commonly paired with flush-mounted device installations in block or concrete walls.
Why this product exists
Masonry walls need boxes sized and shaped for flush mounting before finishing. This style provides the depth, steel construction, and knockout access needed to mount three devices in a single enclosure while fitting typical masonry rough-in practices.
Compared with similar products
Compared with shallower masonry boxes, a 3-1/2 in (89 mm) deep box gives more wiring space for device conductors and splices. Compared with gangable boxes, this welded non-gangable design is intended as a fixed 3-gang solution. If separate power sources must share the same box, compatible partitions may be required to meet applicable Canadian Electrical Code requirements.
