Middle Atlantic 3.4IN TRD SZ Cond FD Assy - 1075CHA

Middle Atlantic 1075CHA Conduit Feed Door Assembly

Overview

The Middle Atlantic 1075CHA is a conduit feed door assembly sized for 3.4-inch trough raceway systems. It provides a finished, code-friendly entry point where conduit penetrates a trough section — eliminating open knockouts and maintaining cable management integrity in structured wiring installations. If you're routing low-voltage cabling through a Middle Atlantic trough system and need a clean, secure conduit transition point, the 1075CHA is the dedicated fitting for that junction. Consult your cable management layout before ordering — trough size and conduit diameter must match.

Compatibility

The 1075CHA is designed for use with Middle Atlantic TRD-series trough raceway systems in the 3.4-inch size class. It fits as a door-style assembly at the conduit entry position on compatible trough sections. Verify your specific trough model number against Middle Atlantic's TRD series documentation to confirm the correct feed assembly variant — other trough sizes require different part numbers. This assembly is not interchangeable with Middle Atlantic's larger or smaller trough feed fittings.

Installation Notes

Install into the designated conduit feed opening on a compatible TRD trough section. The door-style design allows post-installation access for cable additions without full disassembly. Confirm conduit outer diameter clears the feed aperture before pulling wire. No special tools indicated beyond standard low-voltage installation hardware.
