Metallics 50KOSG – Frequently Asked Questions
1) What size knockout does the Metallics 50KOSG seal close off?
The 50KOSG is sized for a 1/2 inch knockout, so it plugs the standard 1/2 inch trade-size opening in a panel, box, or enclosure wall. It is supplied with a gasket, so the hole is closed and sealed rather than just covered.
2) How many knockout seals come in a pack of Metallics 50KOSG?
They ship 10 to a pack, which is how a 1/2 inch knockout seal is normally bought, since an electrician closing unused openings on a panel or a run of boxes will use several on one job.
3) Is the 50KOSG knockout seal steel or plastic?
It is zinc-plated steel, not plastic. The plating is there for corrosion resistance on an electrical enclosure, and the steel body matches the panel wall it is sealing.
4) Should I use a knockout seal or a knockout plug on an unused panel opening?
A sealing washer type like the 50KOSG includes a gasket, which is what you want when the enclosure needs the opening closed against dust or moisture ingress. A plain snap-in or screw-in plug with no gasket just fills the hole mechanically. For a 1/2 inch opening on a panel exposed to damp or dirty conditions, the gasketed seal is the one to specify.
5) Will the 50KOSG fit a 1/2 inch conduit hole as well as a punched knockout?
Yes. A 1/2 inch trade-size knockout and a 1/2 inch conduit entry are the same nominal opening, so the 50KOSG seal and gasket close either one. Where a 1/2 inch connector has been removed from a box or panel, this is the part that closes the hole behind it.
