1-1/2 in Conduit Fitting Hub
This zinc alloy conduit fitting hub provides a threaded connection point for 1-1/2 inch conduit runs. It is designed for electricians and installers who need a durable, corrosion resistant junction in commercial or residential electrical systems. The zinc plated finish protects the hub during extended service in damp or outdoor locations.
1-1/2 in Threaded Hub Size
The single specification that determines fit is the 1-1/2 inch threaded hub diameter. This size must match the conduit trade size exactly to maintain code compliant raceway continuity. No other diameter or thread pitch will engage correctly with this fitting.
Zinc Alloy Construction and Plating
The zinc alloy body with zinc plating resists rust and mechanical damage inside pull boxes or enclosures. It threads directly into a knockout or threaded opening without requiring a separate locknut when the enclosure provides female threads. The hub frees up interior wiring space by sitting flush against the box wall.

Questions about this item
What does the 1-1/2 inch thread size mean when I install this hub in a real electrical box?
The 1-1/2 inch thread matches standard trade-size conduit and box openings, so it screws directly into a compatible knockout or threaded hub without adapters.
How does the threaded NPT interface limit what conduit I can connect?
The tapered NPT threads accept only rigid or IMC conduit with matching 1-1/2 inch trade-size threads; it will not fit EMT set-screw or compression fittings.
What clearance and mounting surface does this zinc-alloy hub need to fit properly?
It requires a 1-1/2 inch threaded knockout or hub opening in a flat metal box or enclosure, with enough wrench flats exposed to tighten the zinc-plated body securely.
