Constructed from steel, it provides a durable, code-appropriate closure that resists tampering and mechanical damage. The screw bar design allows for secure installation without special tooling, making it a reliable solution for electricians working on panel terminations and enclosure sealing tasks. Sized at 2.5 inches, it fits standard knockout openings of that diameter found in a wide range of electrical equipment.\u003c\/p\u003e\n\u003cp\u003eThis knockout seal is suited for residential and commercial electrical installations where unused conduit knockouts must be closed per NEC requirements. It is commonly installed during new construction, renovation, and service calls whenever a knockout is opened but a conduit entry is not used. The 3-piece screw bar configuration allows the seal to clamp securely from the front of the panel or enclosure wall, eliminating the need for access from the back side of the panel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece screw bar design allows single-sided installation without rear access\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003e2.5-inch size fits standard knockout openings of that diameter\u003c\/li\u003e\n  \u003cli\u003eSecures unused knockouts in compliance with NEC enclosure closure requirements\u003c\/li\u003e\n  \u003cli\u003eNo special tooling required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for 2.5-inch knockout openings in residential and commercial electrical panels, junction boxes, and enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician.
