Gardner Bender KO707 – Frequently Asked Questions

1) How does the Gardner Bender KO707 knockout seal install in an unused knockout?
The KO707 seals an open knockout with a single screw. The seal is embossed so it self-centers in the hole, then one screw and bar draw it tight. You can do it from inside or outside the box, which matters when the box is already mounted and you can't get a hand behind it.
2) What is the Gardner Bender KO707 knockout seal made of, and will it rust in a damp panel location?
It's 16-gauge steel, rust-proofed cold-rolled galvanized, and the screw and bar are zinc-plated. That's a corrosion-resistant assembly throughout, not just a plated face.
3) How do I know I'm grabbing the right size seal on the job site?
Each Gardner Bender knockout seal is marked with its size and catalog number right on the part, so once they're loose in a pouch you can still tell them apart. The one you want here is KO707.
4) What thread size is the screw on the KO707 knockout seal?
The KO707 uses a 3/8 inch thread. The screw and bar come with the seal, so there's no separate hardware to order to close the knockout.
5) Is the Gardner Bender KO707 a metal seal or a plastic plug?
Metal. It's a steel knockout seal, not a snap-in plastic plug, so it goes into metal enclosures and panels where a steel closure is what the opening calls for.
6) What manufacturer part number do I order for the Gardner Bender metal knockout seal?
Order it as Gardner Bender KO707. That's the manufacturer part number and the catalog number stamped on the seal itself.
7) How much does a package of KO707 knockout seals weigh for shipping or stockroom planning?
The packaged weight is 38.9 oz, and the package runs 3.88 by 3.75 by 1.13 inches. Useful if you're building out an MRO stock bin or costing a bulk order in.
