Metallics 100KOSG – Frequently Asked Questions
1) What size knockout does the Metallics 100KOSG seal close off?
The 100KOSG is the 1 inch knockout seal, and the size is stamped right on the seal so you can confirm it on the job without measuring. Use it to plug an unused 1 inch opening in a panel or enclosure.
2) What material and finish is the Metallics 1 inch knockout seal, and will it hold up in a wet location?
Steel with a zinc finish. The zinc plating gives it corrosion resistance for general indoor panel and enclosure work, and paired with the gasket it closes the opening against moisture. For heavy washdown or corrosive atmospheres, a stainless or nonmetallic sealing plug is the better call.
3) Can I buy a single Metallics 100KOSG knockout seal, or do I have to order a pack?
These sell in a minimum of 10 each, so plan on a 10-piece buy rather than a single seal. That works out well for panel builders and MRO stock, since unused knockouts tend to show up several at a time on one job.
4) Is the Metallics 100KOSG knockout seal acceptable on a Buy American or ARRA-funded job?
The 100KOSG carries both ARRA compliant and Buy American compliant flags in its product data, which is what institutional and government procurement typically asks for on funded work. Country of origin is listed as multiple, so confirm the origin marking on the carton you receive if your spec requires a single named country.
5) What trades actually use a gasketed knockout seal like the Metallics 100KOSG?
It is aimed at electrical, plumbing, heating and air conditioning work. The common use is an electrician or panel shop closing an unused 1 inch knockout in a panelboard, junction box, or equipment enclosure after a conduit run gets relocated or a circuit is removed, so the box stays closed up.
6) I need knockout seals in sizes other than 1 inch. Does Metallics make them?
The 100KOSG covers the 1 inch knockout, and other sizes and quantities in this gasketed seal line are available by request. If you are closing a mixed panel, pull the knockout diameters first and order by size, since each seal is dedicated to one opening size.
7) How much does a pack of Metallics 100KOSG knockout seals weigh for shipping and truck stock?
Listed at 0.45 lbs, with a packed footprint of 3 in length, 3 in width and 3.6 in height. Small enough to keep a pack in the van without thinking about it.
