Middle Atlantic 418-WH 400 Series Non-Metallic External Elbow Fitting
Overview
The Middle Atlantic 418-WH is an external elbow fitting designed for the Middle Atlantic 400 Series non-metallic raceway system. It provides a clean, direction-change solution at outside corners — the kind of transition point where a straight raceway run needs to turn along a wall edge, column corner, or baseboard perimeter without exposing open wiring or requiring a field-bent conduit workaround. The 418-WH ships in white to match white raceway installations and carries TAA compliance, making it a straightforward fit for government and federally funded projects subject to trade-agreement requirements. If your run is white and your building corners are external, this is the elbow you need.
Compatibility
The 418-WH is purpose-built for the Middle Atlantic 400 Series non-metallic raceway line. It fits external (outside) corner transitions in that system — do not use it for internal corners, which require a separate fitting. Confirm your installed raceway is the 400 Series before ordering; Middle Atlantic's 200 and 300 Series use different fitting profiles that are not interchangeable. The white color designation (-WH suffix) matches white 400 Series raceway channels and covers; if your installation uses ivory or gray raceway, select the corresponding color variant.
