Middle Atlantic WM5781 STL Box Connector 1/2 In.

Overview

The Middle Atlantic WM5781 is a 1/2-inch STL box connector designed for use in structured wiring enclosures and conduit termination applications. This connector bridges conduit runs to wiring boxes or enclosures, providing a secure mechanical transition that keeps cable pathways protected and organized at the entry point. If you're terminating 1/2-in. conduit into a Middle Atlantic enclosure or compatible wiring box, the WM5781 is the correctly sized fitting to maintain a clean, code-appropriate installation.

Compatibility

The WM5781 is sized for 1/2-inch conduit and is intended for use with structured wiring enclosures and low-voltage wiring boxes that accept standard knock-out or conduit entry points. It is compatible with Middle Atlantic STL-series enclosures and other enclosures with standard 1/2-in. KO openings. Verify your enclosure's knock-out diameter before ordering — this connector is spec'd for 1/2-in. trade-size conduit only and is not interchangeable with 3/4-in. or 1-in. fittings.
