Backbox-Surface-Mount, Indoors

The 27193 Series Surface Mount Boxes are multi-gang utility boxes designed for surface mounting where a heavy-duty general purpose box is required. Devices can be mounted to pre-drilled and tapped (#6-32) holes in standard one-gang to five-gang mounting configurations.

The 27193 boxes are finished in a durable baking enamel and are available in eight standard colours Prime coated (gray) versions are available for easy custom finishing to match the decor on site.

They are constructed from heavy duty 16 gauge cold rolled steel (CRS) for maximum durability. The 27193 boxes are easily surface mounted with screws using the mounting holes provided in the back of the box. All boxes are provided with convenient combination 1/2 inch and 3/4 inch conduit knockouts on the top, bottom and rear side. Each box also includes a grounding provision.

The 27193-11-NY is a red single-gang surface box without bottom knockout for use with manual pull stations within the New York City School Construction Authority (NYCSCA).  The Agency regulations will not allow for surface mount boxes with knockouts.  This prohibits tampering with, for example, the internals of a manual pull station.
