The KORA SMB20257 Four Gang Box is designed for reliable electrical connections, measuring 3” x 7 3/8” x 2 1/2” with a spacious 52 cubic inches of capacity. Ideal for various installations, this gang box provides durable support for wiring systems while ensuring easy access and secure mounting for your electrical projects.
The SMB20257 offers 52 cubic inches of usable space. Cubic inch capacity is important for Canadian Electrical Code (CEC) compliance — each conductor, device, and clamp accounts for a set volume, and your total must not exceed the box's rated capacity. At 52 cu. in., this four-gang box provides generous room for higher conductor counts typical in multi-device rough-in work.
Yes, the SMB20257 is designed for standard wall installations. Its 2 1/2" depth suits most conventional stud-wall assemblies. If you're working with shallow walls, specialty framing, or require a specific bracket/nail-on configuration, contact our team with your wall construction details and we'll confirm the right fit.
