The GSA-MB4 mounting bracket lets you install two single-gang Kidde fire alarm modules into a single standard 4-inch square electrical box. Instead of running a separate box for each module, one bracket consolidates the install - less hardware, less conduit, less time on the ladder.
Built for the commercial installer
Steel construction with pre-drilled mounting holes for fast, secure attachment inside standard 4-inch square boxes. Compatible with Kidde single-gang addressable modules including the FX-IDC and FX-CMM input/output families. When a panel layout calls for multiple modules at one location, this bracket cuts the box count in half.

- Standard 4-inch square box compatibility - no special enclosures or custom hardware
