Dupro 1 1/2 EMT Compression Connectors are designed to securely terminate a 1 1/2-inch (40mm) Electrical Metallic Tubing (EMT) conduit to an electrical box or enclosure. These connectors provide a robust, raintight, and often concrete-tight connection, suitable for both dry and damp locations in electrical systems.¹ They are typically made from zinc die-cast or galvanized steel, ensuring durability and corrosion resistance.² The design features a compression mechanism to firmly grip the EMT conduit on one end, and a threaded hub with a locknut on the other end for easy and secure attachment to a knockout.
