Middle Atlantic STL Int. Corner Coupling - G3017TCE

Middle Atlantic G3017TCE Steel Internal Corner Coupling Fitting

Overview

The G3017TCE is an internal corner coupling fitting for Middle Atlantic's 3017-series steel raceway and cord cover systems. This fitting solves the common installation problem of routing cables cleanly through interior 90-degree corners — without exposed gaps or abrupt transitions that compromise both aesthetics and cable protection. Gray finish matches the standard 3017-series raceway color. The G3017TCE is TAA compliant, making it suitable for federal projects and government facilities with domestic sourcing requirements. If you're specifying a complete Middle Atlantic raceway run in a government building, healthcare facility, or commercial office, this fitting keeps the installation consistent and compliant at every interior corner.

Compatibility

Designed for use with Middle Atlantic's 3017-series steel raceway and cord cover products. The 3017 designation refers to the 3/4-inch by 1-3/4-inch profile steel raceway line. Confirm your base raceway matches the 3017 profile before ordering — this coupling is profile-specific and will not fit narrower 2010-series or wider 4010-series raceways. Pair with the corresponding external corner coupling (G3017TCE handles inside corners; a separate external fitting is required for outside corners) and straight couplings to complete a fully enclosed cable management route.
