Dupro 1 EMT Compression Connectors are designed to securely connect a 1-inch (25mm) Electrical Metallic Tubing (EMT) conduit to an electrical box or enclosure. These connectors provide a durable, raintight, and often concrete-tight seal, making them appropriate for use in both dry and damp locations within electrical installations. They typically consist of a compression mechanism that firmly grips the EMT conduit on one end, and a threaded portion with a locknut on the other end for attachment to a knockout opening. Dupro connectors are commonly constructed from materials such as zinc die-cast or galvanized steel, ensuring reliable performance, mechanical protection, and proper grounding for the electrical wiring.
