Metallics 75KOSG – Frequently Asked Questions
1) What size knockout does the Metallics 75KOSG knockout seal fit?
The 75KOSG is sized for a 3/4 inch knockout, the standard KO opening in a panel, box, or enclosure. It plugs an unused 3/4 inch hole and comes with a gasket for the seal.
2) Do I need a knockout seal or a conduit plug for an unused hole in my panel?
Two different parts. A knockout seal like the 75KOSG closes an unused, unthreaded knockout punched in sheet metal, held by its gasket and clamping action. A threaded conduit plug closes a threaded hub or fitting opening instead. If the hole is a bare 3/4 inch KO in a box or panel wall, the seal is the right part.
3) Does the Metallics 75KOSG come with a gasket, or do I order that separately?
The gasket ships with it. The 75KOSG is a knockout seal and gasket together, so you have both halves needed to close off the opening without buying a separate sealing washer.
4) How many Metallics 75KOSG knockout seals come in a pack?
They come 10 to a pack. That makes it a practical MRO stock item for panel work, where you typically close several unused 3/4 inch knockouts across a job rather than one.
5) What is the Metallics 75KOSG made of and will it hold up in a damp panel location?
It is steel with a zinc finish, which is the usual plating for knockout seals used in indoor and general panel work. The included gasket is what forms the seal against the enclosure wall.
6) What is the Metallics part number for a 3/4 inch knockout seal with gasket?
75KOSG. That is the Metallics manufacturer part number for the 3/4 inch knockout seal with gasket, sold 10 per pack.
