Middle Atlantic NM Three DEV Mount Bracke - 5450A3WH

Middle Atlantic 5450A3WH Three-Device Non-Metallic Rack Mount Bracket

Overview

The 5450A3WH is Middle Atlantic's white, non-metallic three-device mounting bracket from the 5400-series raceway fitting line. Measuring 3.5 in (8.9 cm) tall and 7.5 in (19.1 cm) wide, it fits into standard raceway channels and gives you a dedicated, organized mount point for up to three low-voltage devices — keystones, inserts, or small modules — without resorting to ad-hoc surface mounting or cutting custom holes. TAA-compliant construction makes it a clean fit for government and federally-funded projects. The white finish matches standard white raceway installations; if your raceway is a different color, verify finish compatibility before ordering.

Compatibility

Designed for use within the Middle Atlantic 5400-series non-metallic raceway and cord cover system. The bracket accepts standard keystone inserts and device modules that conform to the 5400-series fitting interface — confirm insert dimensions against the 7.5 in width and 3.5 in height before specifying. Not intended for metallic raceway systems or standalone surface-mount applications outside the 5400-series channel profile.

Installation Notes

Mounts within the 5400-series raceway channel per the raceway system's standard fitting procedure — no specialized tools beyond basic hand tools required. Verify that your raceway run has sufficient depth and channel width to accept the 7.5 in bracket width without conflict from adjacent fittings or wire fill. TAA compliance applies to the bracket itself; confirm TAA status of any inserted devices separately if the full assembly must meet federal procurement requirements.
