The Bridgeport 1" 143 Zinc-Plated Steel Raintight Sealing Conduit Locknut securely fastens threaded conduit to an unthreaded opening in a box or enclosure in a wet location. Contractors can run into difficulties when securing conduit to an electrical box when water is present. The PVC seal creates a raintight seal protecting the connection from the elements. The zinc-plated steel body is corrosion resistant for long-term use. Bridgeport locknuts come in a wide range of sizes and styles to provide complete installation flexibility, helping you install fast and deliver more. We engineer our locknuts 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.
