Middle Atlantic STL Device BOX 3G White - 5748-3WH

Middle Atlantic 5748-3WH Steel Device Box Fitting — White

Overview

The Middle Atlantic 5748-3WH is a white steel device box fitting designed for use within the Middle Atlantic 500 and 700 Series raceway and cord cover systems. It provides a clean, finished mounting point for switches and receptacles directly within the raceway channel — eliminating the need for separate surface-mount boxes and keeping low-voltage wiring runs organized and code-compliant in commercial environments. The 5748-3WH finishes in white to match standard interior raceway installations and carries TAA compliance, making it eligible for government and federally funded projects where country-of-origin requirements apply.

Compatibility

This fitting is purpose-built for the Middle Atlantic 500 and 700 Series switch and receptacle raceway systems. It is intended for installations where a standard 3-gang device opening is required within the raceway body — accommodating standard decorator-style switches, outlets, and low-voltage inserts. Confirm your raceway series and gang count against the 5748-3WH before ordering; Middle Atlantic offers single- and multi-gang variants for this series, and selecting the correct gang count is the primary fit consideration. If you are pairing this with power distribution or structured wiring components in the same run, verify raceway channel depth to ensure the box fitting seats flush without interference.
