Weatherproof Plugs

Shop weatherproof plugs for sealing unused threaded openings in electrical boxes, conduit bodies, enclosures, hubs, and other compatible fittings. These closure plugs help block rain, moisture, dust, dirt, and debris while providing a clean, finished installation in indoor, outdoor, and exposed environments.

The collection includes durable metal plugs in common trade configurations for use across electrical, telecom, broadband, utility, industrial, and commercial projects. Threaded construction allows installers to close unused conduit entries, spare hubs, and open connection points during new construction, equipment changes, system upgrades, and repair work.

Weatherproof plugs are useful wherever a threaded opening needs to be closed without replacing the surrounding component. Common applications include surface-mounted boxes, junction boxes, conduit bodies, equipment enclosures, raceway fittings, and infrastructure installed at wireless sites, equipment shelters, rooftops, charging stations, utility facilities, and outdoor equipment areas.
