The Bridgeport 156-DC 2" Rigid to Enclosure Die Cast Zinc Insulated Threaded Hub is your solution for connecting threaded rigid service entrance conduit to a box or enclosure. The NPSM threads create a pressure-tight, vibration-resistant seal when the male and female threads compress and tighten. Featuring an insulated throat, the hub can withstand temperatures up to 105°C. The threaded hub has a concrete tight seal that prevents contaminants from abrading conductor insulation or effectively reducing the area inside the raceway. The hub’s zinc die cast construction is ideal for long-term use. Bridgeport threaded hubs come in a wide range of sizes and styles to provide complete installation flexibility, helping you install fast and deliver more. We engineer our hubs with quality and innovation, allowing contractors to save time and money on every job. When you need quality electrical fittings for more efficient jobs, look for Bridgeport Orange.
