Middle Atlantic NM Coupling 300 Ivory - 306

Middle Atlantic 306 Non-Metallic Raceway Coupling Fitting

Overview

The Middle Atlantic 306 is a non-metallic coupling fitting designed to join sections of Middle Atlantic's Middle Atlantic 300-series raceway end-to-end. In ivory finish, it blends with standard commercial wall and ceiling installations where surface-mount raceway and cord cover systems run exposed. The 306 solves the practical problem of maintaining a clean, continuous raceway run across joints — without gaps that expose cabling or interrupt the finished appearance of a structured wiring installation. TAA compliant, making it suitable for federal, state, and local government projects with domestic-sourcing requirements.

Compatibility

The 306 couples sections within the Middle Atlantic 300-series non-metallic raceway family. Specify this fitting when your installation uses 300-series ivory raceway base and cover — it is sized and profiled to match that series specifically. Do not mix with fittings from other raceway series (e.g., 200-series or 700-series), as channel dimensions differ. For matching inside corners, outside corners, and end caps in the same ivory finish, source companion fittings from the 300-series accessory set to maintain a consistent installation.

Installation Notes

Slide the 306 over the abutting ends of two 300-series raceway sections to bridge the joint. No tools or adhesives are required for the coupling itself — the fitting relies on the raceway's channel geometry for alignment and retention. Ensure raceway sections are cut cleanly and squarely before joining; ragged cuts prevent the coupling from seating flush and can leave visible gaps. In TAA-sensitive projects, confirm the full raceway bill of materials — base, cover, and all fittings — carries TAA-compliant status before procurement sign-off.
