Ocal HUB3-G PVC-Coated Zinc Knockout Hub, 3-Inch Trade Size

Thomas & Betts HUB3-G Ocal® PVC-Coated Zinc Knockout Hub, 3-Inch Trade Size

The Thomas & Betts HUB3-G is a 3-Inch Ocal® PVC-Coated Zinc Knockout Hub engineered to provide a secure, corrosion-resistant conduit connection point for electrical enclosures, panels, and equipment housings. Built on a durable zinc base and finished with a factory-applied PVC coating, this knockout hub is designed for installations exposed to moisture, chemicals, and harsh industrial atmospheres where uncoated fittings would quickly corrode. The 3-Inch trade size allows direct installation into standard enclosure knockouts, giving electricians and maintenance crews a dependable, long-lasting entry point for conduit runs into panelboards, motor control centers, and outdoor equipment housings. The Ocal® PVC-coating system is widely specified for wastewater, chemical processing, and coastal facilities where standard fittings fail prematurely.
