The VALUE COLLECTION BD-17482 is a steel snap-in blank designed to close unused 1-inch knockout openings in electrical enclosures, panels, and junction boxes. The snap-in design allows for tool-free or minimal-tool installation, seating securely into standard 1-inch knockouts without hardware. Fabricated from steel, the blank provides a durable, code-appropriate closure that keeps enclosures protected from dust, debris, and incidental contact. Electricians and electrical contractors install these blanks during rough-in and finish work on both new construction and retrofit projects.
This blank is rated for use with 1-inch Intermediate Metal Conduit (IMC) and Rigid Metal Conduit (RMC) knockout openings. It is suited for residential, commercial, and light industrial electrical installations wherever unused conduit knockouts require closure. Sold in a package of 10, making it practical for panel work and multi-enclosure jobs where several openings need to be filled in a single visit.
Designed for use with Intermediate Metal Conduit (IMC) and Rigid Metal Conduit (RMC) knockout openings sized at 1 inch.
Installation is performed by licensed electricians in accordance with applicable NEC requirements for enclosure integrity. De-energize all circuits and verify the panel or enclosure is confirmed dead before working inside. Align the blank over the knockout opening and press firmly until the snap-in tabs seat flush against the enclosure wall. Inspect the installed blank to confirm it sits flat and will not dislodge under normal service conditions.
