System Sensor SPBBSW — Surface-Mount Back Box “Skirt” for Wall-Mount Devices
The System Sensor SPBBSW is a white surface-mount back-box skirt accessory designed for use with wall-mounted notification appliances (horns, strobes, speaker-strobes) from the System Sensor SpectrAlert Advance and other compatible lines. It acts as a mounting and aesthetic trim plate that covers rough wall surfaces or conduit feed details, providing a clean finished appearance and facilitating installation of devices on non-flush or surface mount wiring.
