Middle Atlantic 5782A 3/4-Inch Steel Conduit Connector
Overview
The Middle Atlantic 5782A is a 3/4-inch (19.1 mm) galvanized steel conduit connector designed for use with Middle Atlantic's 500 and 700-series steel raceway systems. It provides a secure, code-friendly transition point where conduit enters a raceway run — keeping cable management tight and compliant in commercial AV, security, and structured cabling installations. TAA compliance makes the 5782A a straightforward procurement choice for government and federally funded projects. Include it wherever your raceway design calls for a 3/4-inch conduit entry rather than a direct home-run pull.
Compatibility
The 5782A is specified for Middle Atlantic's Middle Atlantic 500-series and 700-series 12-inch steel raceway and cable management products. The 3/4-inch trade-size diameter (19.1 mm) mates with standard 3/4-inch EMT, rigid, or IMC conduit, which covers the majority of low-voltage and power conduit runs in typical rack and wall-mount infrastructure. If your run uses 1/2-inch or 1-inch conduit, select the matching connector size from the same fitting family rather than forcing a fit with the 5782A — conduit connectors are not adjustable. Pair with compatible raceway systems and racks and enclosures for a complete managed pathway.
Installation Notes
The galvanized steel construction provides corrosion resistance suitable for above-ceiling and wall-cavity runs in conditioned spaces. Verify conduit trade size before ordering — 3/4-inch trade size has an actual OD of approximately 1.050 inches (26.7 mm), which is distinct from the 19.1 mm knockout dimension this fitting seats into. Standard conduit installation tooling applies; no special tools are required beyond what a typical low-voltage or electrical rough-in kit provides.
