Metallics 250KOSG – Frequently Asked Questions
1) What size knockout does the Metallics 250KOSG seal close off?
The 250KOSG is sized for a 2-1/2 inch knockout, which is the trade size opening left in a panel, box, or enclosure when a 2-1/2 inch conduit fitting is removed or never used. It will not fill a smaller or larger knockout, so match the trade size of the open hole before ordering.
2) Does the Metallics 250KOSG knockout seal come with a gasket?
A gasket is included with the 250KOSG seal. The gasket sits between the seal and the enclosure wall so the closed knockout stays tight against dust and moisture ingress rather than just being covered mechanically.
3) Is the Metallics 2-1/2 inch knockout seal steel or plastic?
Steel, with a zinc finish. That makes it the right choice where a metal closure is wanted on a steel panel or enclosure, as opposed to a snap-in plastic plug.
4) What part number do I order for a 2-1/2 inch Metallics knockout seal with gasket?
Order Metallics 250KOSG. That is the manufacturer part number for the 2-1/2 inch steel zinc knockout seal supplied with a gasket, ten per package.
5) Can I use a knockout seal instead of a conduit plug on an unused panel opening?
They do different jobs. The Metallics 250KOSG is a knockout seal with gasket, meant to close an open 2-1/2 inch knockout in a box, panel, or enclosure wall. A conduit plug threads into the end of a raceway or a threaded hub, not into a punched knockout. If the hole is a stamped knockout in sheet metal, the seal is the correct part.
6) How many pieces are in a package of Metallics 250KOSG knockout seals?
Ten seals per package. For MRO stock or a panel build with several unused 2-1/2 inch knockouts, one package covers ten openings, each with its gasket.
