Knockout seal for 2-inch conduit

The Gardner Bender KO706 is a 16-gauge steel knockout seal designed for 2-inch conduit openings. It suits electricians and maintenance crews who need to close unused knockouts in junction boxes or enclosures. The cold-rolled galvanized steel resists rust in damp or outdoor locations. One screw secures the seal from either side of the box.

Pack of 100 seals for batch work

Each order supplies 100 pieces, giving enough stock for multiple job sites or a large panel build. The 16-gauge thickness provides mechanical protection for the opening but is not a structural reinforcement. Once the screw is tightened the seal stays fixed; it is not intended for frequent removal and reinstallation. The quantity covers typical commercial rough-in requirements.

Self-centering emboss and marked sizing

An embossed ring centres the seal automatically in the knockout, reducing alignment time. The screw and mounting bar are zinc-plated for corrosion resistance matching the body. Size and catalogue number are stamped on the face for quick verification during inspection. No separate gasket or adhesive is required for installation.

Questions about this item

Will the 2-inch knockout seal fit the 16-gauge steel boxes I already have?

The seal is made from 16-gauge steel and is embossed for self-centering in standard 2-inch knockouts, so it aligns with boxes of the same gauge and knockout size.

How can I confirm the Gardner Bender KO706 seal is installed correctly?

The single screw tightens the zinc-plated bar against the inside or outside of the box; when the seal sits flush and the embossed centering marks align with the knockout edge, it is seated properly.

Does the pack of 100 include the mounting screws or do I buy them separately?

Each seal comes with its own zinc-plated screw and bar already assembled, so the box of 100 provides all hardware needed for installation.
