Dual Module Mounting Bracket for 4-Inch Square Electrical Box
SKU KD-GSA-MB4
- Fast shipping from four branches
- 30-day returns on unopened products
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
- Steel construction with pre-drilled holes for secure, repeatable mounting

FAQs
How many modules can I fit with the GSA-MB4?
Two single-gang Kidde fire alarm modules per bracket. Each module mounts in its own gang position inside a standard 4-inch square electrical box.
What modules are compatible with this bracket?
Kidde single-gang addressable modules, including the FX-IDC input module and FX-CMM control module families. Any Kidde module designed for single-gang box mounting will fit.
Does this bracket require a special electrical box?
No. It fits standard North American 4-inch square electrical boxes. No proprietary enclosures or custom hardware needed.
Why use this bracket instead of two separate single-gang boxes?
Consolidating two modules into one 4-inch square box cuts your box count in half at that location, reducing conduit runs, hardware cost, and installation time.
