The NESCO SCI-12 is a 1-1/4" 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 guards wire insulation against abrasion during pull-through — a key advantage on mid-size conduit runs where conductor damage means costly rework. The steel body provides solid mechanical strength and reliable grounding continuity, making the SCI-12 a dependable choice for sub-panel feeds, junction box terminations, and branch circuit rough-in work where a secure, code-compliant EMT connection is required.
