Middle Atlantic 5790B Steel Armored Cable Connector Fitting

Overview

The Middle Atlantic 5790B is a steel armored cable connector fitting designed to terminate and secure armored cable runs entering raceway enclosures. At 2 in × 0.63 in × 1 in deep, the 5790B occupies minimal panel real estate while providing a clean, strain-relieved entry point — the right detail on installations where cable management discipline matters as much as device placement. TAA compliance makes it a straightforward fit for federal and government-funded security projects without requiring a separate compliance review on this component.

Compatibility

The 5790B is part of Middle Atlantic's Middle Atlantic raceway and cord cover line, specifically engineered for the 500 Series and 700 Series steel armored cable connector fitting applications. Pair it with compatible cable management raceway from those series when routing armored cable through structured pathways in AV, security, or network infrastructure enclosures. Confirm the armored cable outside diameter against the fitting's entry bore before ordering — this fitting targets the specific OD range the 500/700 series hardware is designed around. If your run uses standard non-armored cable, a standard cord cover fitting from the same series is the correct choice instead.

Installation Notes

Mount orientation follows standard raceway fitting practice — the 1 in depth dimension accounts for the connector body seated flush against the raceway wall. No special tooling is called out in the evidence beyond what armored cable termination normally requires. Verify raceway knockout size matches the 5790B's thread or body diameter before cutting; the compact 2 in width means it fits densely populated raceway sections without conflict between adjacent fittings.
