Middle Atlantic 175CHA-LJB 1-Gang 3/4in Conduit Housing
Overview
The Middle Atlantic 175CHA-LJB is a 1-gang conduit housing designed for 3/4-inch conduit terminations in structured wiring and rack system installations. It provides a clean, code-compliant transition point where conduit runs meet wall or enclosure surfaces — the kind of detail that keeps a professional installation looking intentional rather than improvised. If you're routing signal or power cabling through EMT or rigid conduit into a Middle Atlantic enclosure or wall box, the 175CHA-LJB handles the interface without improvised fittings or exposed knockouts.
Compatibility
Designed for use with rack and enclosure accessories in Middle Atlantic's product ecosystem. The 1-gang form factor fits standard single-gang wall plate openings and enclosure cutouts. The 3/4-inch conduit entry matches the most common EMT conduit size used in commercial low-voltage and power wiring runs — the size you'll encounter in the majority of security, AV, and structured cabling rough-ins. Verify cutout dimensions against your specific enclosure or wall box before ordering; Middle Atlantic's 1-gang accessories follow consistent sizing across the line, but confirm against your panel or housing spec sheet. Suitable for use alongside cable management components in the same installation.
Installation Notes
Install into a standard 1-gang opening. Secure conduit using a compatible 3/4-inch conduit connector or locknut at the housing entry — the housing itself provides the mechanical interface, not the conduit clamp. Ensure conduit is properly reamed and deburred before pulling cable through to prevent insulation damage. Follow local electrical and low-voltage codes for conduit fill and bonding requirements.
