The OHLECTRIC Type S Steel Screw-In Knockout Seal is designed to close exposed knockout holes in electrical boxes, panels, and enclosures. Made from galvanized steel, this knockout seal helps protect open knockouts from exposed wiring, debris, and accidental contact.
The screw and bar design allows for a secure fit in standard knockout openings and is especially useful for old work applications or finished boxes where removing devices or covers is not practical. Ideal for electricians, contractors, maintenance teams, and general electrical installations.
