The NESCO SCI-20 is a 2" insulated steel set screw connector designed for use with EMT (Electrical Metallic Tubing) in commercial and residential electrical installations. Built for professional electricians and contractors, its insulated throat protects wire insulation from abrasion during pull-through — a critical detail on larger conduit runs where conductor damage can mean costly rework. The steel construction provides solid mechanical strength and reliable grounding continuity, making it a dependable choice for panel feeds, junction box connections, and branch circuit rough-in work where a secure, code-compliant EMT termination is required.
