3-Inch Threaded Conduit Hub

The L.H. DOTTIE WTH300 is a zinc alloy conduit fitting hub designed for 3-inch threaded connections. It provides a secure junction point for protecting and routing electrical cables in commercial or industrial installations. The durable metal construction resists corrosion and mechanical stress in exposed locations.

Threaded Interface Constraints

The hub relies on standard 3-inch threaded conduit entries for a rigid, weather-tight seal. Installation requires compatible threaded pipe or fittings; it cannot connect to non-threaded or push-fit systems without adapters. The connection integrity depends on proper thread engagement and tightening to maintain grounding continuity.

Capacity and Headroom

The 3-inch trade size accommodates large cable bundles or multiple conductors typical of feeder runs. It handles heavy-gauge wiring pulling forces without deformation. The hub is not suited for smaller conduit sizes or low-voltage data-only pathways where a reduced fitting would be more appropriate.

Questions about this item

How do I choose the right size of this conduit hub for my installation?

Select the 3 in version when your conduit and enclosure entries are both three inches; the hub is offered in this single trade size.

What does the 3 in rating mean when the hub is installed?

It indicates the hub accepts three-inch threaded conduit and fits a three-inch knockout, providing a secure mechanical connection.

What thread standard does the hub use and what does it limit?

The hub uses standard NPT threading, which limits the connection to three-inch rigid or IMC conduit with matching threads.
