It fits 1-1\/2 inch conduit openings and is listed for use with rigid metal conduit and intermediate metal conduit (IMC) installations. The plug maintains enclosure integrity by closing open knockouts, helping to prevent contamination, debris ingress, and unauthorized access to wiring. It meets NFPA 70, UL 514B, and CSA standards, making it a code-compliant solution for both new construction and retrofit applications. Electricians and electrical contractors install this plug during panel builds, junction box work, and enclosure finishing tasks.\u003c\/p\u003e\n\u003cp\u003eThis knockout plug is suited for residential, commercial, and light industrial electrical installations wherever an unused 1-1\/2 inch knockout needs to be closed. Common applications include panelboards, junction boxes, pull boxes, and other metallic or non-metallic enclosures. It is installed after conduit routing is complete and remaining open knockouts must be sealed per NEC requirements. The thermoplastic construction resists corrosion and provides a secure, lasting fit in standard knockout openings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeals unused 1-1\/2 inch conduit knockouts in electrical enclosures\u003c\/li\u003e\n  \u003cli\u003eListed for use with rigid metal conduit and IMC conduit systems\u003c\/li\u003e\n  \u003cli\u003eThermoplastic construction resists corrosion and moisture\u003c\/li\u003e\n  \u003cli\u003eCompliant with NFPA 70 (NEC), UL 514B, and CSA File 4484 and LR589\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rigid metal conduit and intermediate metal conduit (IMC) conduit systems.
