The NESCO SCI-05 is a 1/2" 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 key detail on high-volume rough-in work where conductor damage means costly callbacks. The steel body delivers solid mechanical strength and reliable grounding continuity, making the SCI-05 a staple fitting for device box connections, branch circuit rough-in, and panel terminations where a fast, secure, code-compliant EMT connection is required.
