3-Piece Carbon Steel Knockout Seals, 3-1/2 in., 10-Pack

These 3-piece knockout seals are for electricians and maintenance professionals who need to cover exposed knockout openings in metal enclosures or outlet boxes. They provide a practical way to close unused openings while working around existing wiring.

Made of carbon steel with a silver finish, each seal is designed for 3-1/2-inch knockout openings. A screw passes through the seal and threads into a strap positioned on the opposite side of the opening to hold it in place. The seals can be installed from either the inside or outside of the box without rearranging wires. Pack includes 10 seals.

Key Features:

• Three-piece design: Covers exposed knockout openings in metal enclosures and outlet boxes.
• Inside or outside installation: Allows placement from either side of the box without moving existing wires.
• Screw-and-strap attachment: Secures the seal through the opening with a threaded strap on the opposite side.
