Middle Atlantic G3018AE STL External Corner Coupling Fitting
Overview
The Middle Atlantic G3018AE is a steel external corner coupling fitting designed to join sections of 3018AE steel raceway at outside corners. Where cable runs need to change direction at a wall or structural corner, this fitting maintains a clean, enclosed pathway — keeping conductors protected and the installation looking finished rather than patched together with field-bent conduit. The G3018AE ships in gray to match the standard 3018AE raceway finish, so transitions blend with the rest of the run.
Compatibility
Designed specifically for the Middle Atlantic 3018AE steel raceway system. Fits the 3018AE raceway profile — do not use with 3018 non-AE variants or other raceway widths, as coupling geometry is profile-specific. If you are building out a structured cable management run with 3018AE straight sections, inside corners, and couplers, the G3018AE handles the outside corner transitions in that same system.
Installation Notes
TAA Compliant and Canadian Certified, making it eligible for U.S. federal projects subject to the Trade Agreements Act and installations requiring Canadian certification. Confirm your full raceway run uses 3018AE-series components throughout — mixing raceway profiles within a single run creates fitment gaps that defeat the purpose of an enclosed system.
