Gardner Bender KO701 – Frequently Asked Questions

1) What size knockout does the Gardner Bender KO701 metal knockout seal fit?
The KO701 seal is built for 3/8 inch thread knockouts, and the embossed self-centering ring drops it into the opening square without fiddling. Size and catalog number are stamped right on the seal, so if you are pulling one out of a mixed bin on a job you can confirm the size before it goes in the panel.
2) Can I install a knockout seal if I can only reach the outside of the panel?
Yes. The Gardner Bender KO701 installs from either side of the box, inside or outside, which matters when the enclosure is already full of conductors or mounted tight to a wall. One screw draws the bar up behind the knockout and holds the seal in place, so it is a one-tool job.
3) Is a metal knockout seal better than a plastic snap-in plug for an unused knockout?
For commercial and industrial enclosures, a steel seal like the KO701 is the one most electricians reach for: 16-gauge rust-proofed cold-rolled galvanized steel with zinc-plated screw and bar, so it holds up in damp mechanical rooms and outdoor-adjacent gear where a plastic plug gets brittle. Plastic snap-ins are quicker for a residential junction box you will never revisit. If the panel is subject to abuse, corrosion, or inspection, go metal.
4) Do I need any extra hardware to install the Gardner Bender KO701?
No separate hardware to buy. The seal comes with its own zinc-plated screw and bar, and that single screw is all that holds it. You just need a screwdriver or nut driver to suit the screw head.
5) Will a galvanized steel knockout seal hold up in a damp industrial enclosure?
Corrosion resistance is the point of this one. The body is rust-proofed cold-rolled galvanized steel and the screw and bar are zinc plated, so all three pieces are coated rather than just the face plate. It is used on electrical panels, junction boxes, and industrial enclosure maintenance work for that reason.
