Middle Atlantic STL Int. Corner Coupling - 2017TC

Middle Atlantic 2017TC STL Interior Corner Coupling

Overview

The Middle Atlantic 2017TC is an interior corner coupling designed for use with Middle Atlantic's STL (Slim-Line) rack and enclosure framing systems. The 2017TC connects structural frame members at interior corners, maintaining alignment and rigidity at junction points within a multi-section or custom-configured rack enclosure build. If you're assembling or extending an STL-series enclosure and need a mechanical connector to secure interior corner joints, this is the part that keeps the frame square and load-bearing.

Compatibility

The 2017TC is designed for Middle Atlantic STL-series rack enclosure frames. Verify compatibility with your specific STL enclosure configuration — Middle Atlantic's STL line spans a range of rack unit heights and widths, and corner coupling requirements vary by frame geometry. Consult the enclosure assembly documentation for your specific STL model to confirm this coupling applies to your interior corner count and frame profile. It is not interchangeable with fittings from Middle Atlantic's BGR, ERK, or PD enclosure lines without verification.

Installation Notes

Install during the initial frame assembly sequence — retrofitting interior corner couplings into a fully populated rack requires partial disassembly of the frame. Ensure all mating frame extrusions are fully seated before torquing fasteners to prevent angular misalignment that compounds across multi-section builds. Use Middle Atlantic's recommended tooling and follow the STL assembly guide for correct fastener sequence.
