Middle Atlantic STL Extra Deep DEV BOX 2G - R5753

Middle Atlantic R5753 Extra Deep Alarm Device Box Fitting

Overview

The R5753 is an extra deep alarm device box fitting from Middle Atlantic's 500 and 700 Series raceway and cord cover line. Finished in red, it provides a dedicated enclosure for alarm device mounting within surface-mounted raceway runs — the right answer when standard-depth device boxes won't accommodate the wiring volume or connector depth behind a detector, sounder, or pull station. The R5753 is TAA-compliant, making it a straightforward fit for government and federally funded installations with domestic-sourcing requirements.

Compatibility

Designed for use with Middle Atlantic 500 Series and 700 Series steel raceway and cord cover systems. Verify your raceway series and device box footprint before ordering — the extra deep profile is specifically suited to installations where standard device boxes restrict conduit entry or device mounting depth. For broader raceway and cable management planning, confirm fitting dimensions match the installed raceway channel width. This fitting does not apply to Middle Atlantic rack enclosure or AV furniture product lines.

Installation Notes

Mount within the 500 or 700 Series raceway run at the alarm device location. The red color coding provides at-a-glance identification of alarm circuit boxes during inspections and service calls — useful in multi-circuit raceway installations where distinguishing alarm runs from data or low-voltage power is a compliance or maintenance requirement. TAA compliance should be documented at the project level; retain purchase records confirming country of origin for audit purposes.
