Hubbell 5271-0 1 Inch Conduit Plug Pack of 4

Product Description

The HUBBELL 5271-0 is a 1-inch conduit plug sold in a pack of 4. Conduit plugs are used to seal the open ends of conduit fittings, enclosures, or knockout openings when a conduit run is not present or when a fitting needs to be temporarily or permanently closed. This fitting is installed by licensed electricians during rough-in and finish electrical work to maintain enclosure integrity and meet code requirements for closed wiring systems.

This plug is suited for residential and commercial electrical installations where unused conduit entries must be closed. Common applications include panelboards, junction boxes, conduit bodies, and electrical enclosures with 1-inch threaded or knockout openings. The pack-of-4 format is practical for service vehicles and job sites where multiple closures are needed in a single visit.

Key Features

Installation Notes

Installation is performed by a licensed electrician. De-energize and lock out the enclosure before working on any open conduit entry or box.
