The NESCO SCI-40 is a 4-inch steel set screw connector with an insulated throat, engineered for professional electricians and contractors working with large-diameter rigid metal conduit (RMC) or intermediate metal conduit (IMC). Built to handle the demands of commercial and industrial job sites, this connector delivers a secure, vibration-resistant connection to enclosures and junction boxes while protecting conductors from abrasion at the entry point. Whether you're roughing in a service entrance, pulling wire through a panel knockout, or completing a large-scale commercial fit-out, the SCI-40 keeps your installation clean, code-compliant, and built to last.
