Metallics 1501KOSGSSWN – Frequently Asked Questions
1) What size knockout does the Metallics 1501KOSGSSWN seal close off?
It is sized for a 1-1/2 inch knockout. The 1501KOSGSSWN is a stainless steel knockout seal supplied with a gasket, so it plugs an unused 1-1/2 inch opening in a box, panel or enclosure rather than being used on a different trade size. For other knockout sizes you need the matching size in the same seal line.
2) Does the Metallics 1501KOSGSSWN knockout seal come with a gasket, or do I order that separately?
The gasket ships with it. The 1501KOSGSSWN is a seal and gasket assembly, so you are not buying the sealing washer as a separate line item. That is the part that keeps the plugged knockout from leaking at the enclosure wall.
3) Why use a stainless steel knockout seal instead of a plastic or steel snap-in plug?
Stainless resists corrosion, which is the reason to pick the 1501KOSGSSWN over a plain steel or plastic plug on wash-down, food processing, coastal, or outdoor enclosures. Plastic snap-in plugs are quicker and cheaper for dry indoor panels; the stainless seal with its gasket is what you reach for when the enclosure has to stay sealed and the plug cannot rust out.
4) Do I need a knockout seal for an unused 1-1/2 inch hole in my panel?
Yes. An open knockout leaves the enclosure unsealed and is a code callout on inspection, and a 1-1/2 inch hole is large enough to defeat the whole enclosure rating. The Metallics 1501KOSGSSWN fills that 1-1/2 inch opening with a stainless seal and gasket so the panel closes up properly.
5) Is the Metallics 1501KOSGSSWN a conduit fitting or just a hole plug?
It is a hole plug, not a raceway fitting. Nothing terminates into it. The 1501KOSGSSWN closes a 1-1/2 inch knockout you are not using. If you need to land 1-1/2 inch conduit at that opening, you want a connector or hub instead.
