The NESCO 3" Insulating Bushing (Model 1668) is a code-required fitting designed to protect conductor insulation at large conduit terminations. Its smooth insulating throat prevents wire nicking and abrasion during pull-through — a critical safeguard on commercial and industrial rough-ins where 3" EMT or rigid conduit terminates at panels, service entrances, or industrial enclosures. Threads directly onto conduit end with no tools required, making it a fast, reliable choice for electricians working under tight schedules on the job site.
