KORA SMB20186 STEEL STUD GANGABLE BOX WITH KNOCK OUT 3”X 2”X 2 1/2”, 16 CU. INCH (3104-KSSX)

A gangable box is designed so that its side walls can be removed and individual boxes bolted together, creating a wider multi-gang enclosure for switches, receptacles, or other devices. To gang the KORA SMB20186 units, simply remove the common side knock-out or removable side plate between adjacent boxes and fasten them together before mounting to the steel stud. This lets you install two, three, or more devices side-by-side in a single assembly.

Yes — the SMB20186 is specifically designed for steel stud framing, making it well suited for both residential and commercial construction. Its steel construction provides durability in commercial environments, and the gangable design meets the flexibility demands of multi-device commercial installations. Always verify that your specific application complies with local Canadian Electrical Code (CEC) requirements and your authority having jurisdiction (AHJ).

Under the Canadian Electrical Code (CEC) Rule 12-3034, each conductor entering a box must be counted against the box's volume, with each conductor volume determined by its wire gauge (e.g., 14 AWG = 2.0 in³, 12 AWG = 2.25 in³). Devices, clamps, and ground wires also count toward the fill calculation. For a 16 in³ box with 14 AWG wiring, you can typically accommodate up to 8 conductor equivalents. If your application requires more capacity, contact our team and we can help you find a larger or deeper box to suit your needs.
