Metallics 125KOSG – Frequently Asked Questions
1) What size knockout does the Metallics 125KOSG seal close off?
The 125KOSG is sized for a 1-1/4 inch knockout in a panel box, enclosure, or gutter. The size is stamped right on the seal, so once it is in a bin with other sizes you can still tell them apart.
2) Do I need a separate gasket to make a 1-1/4 inch knockout seal weathertight?
No separate gasket to buy. The Metallics 125KOSG ships as a gasketed knock-out seal, so the sealing washer comes with the assembly.
3) Does the 125KOSG meet Buy American requirements for a public project?
The 125KOSG knock-out seal is flagged as both Buy American compliant and ARRA compliant in the manufacturer record, which is what a government, school, or healthcare procurement office typically needs on file for a federally funded job.
4) What if the open knockout in my panel is not 1-1/4 inch?
Use a seal stamped for the actual knockout size. The 125KOSG only suits 1-1/4 inch openings; Metallics makes the same gasketed knock-out seal in other sizes and pack quantities, so match the seal to the hole rather than trying to bridge a larger opening.
5) How many pieces come in one Metallics 125KOSG knockout seal?
Each 125KOSG assembly is 4 pieces: the seal plate, gasket, and the fastening hardware that draws it up against the panel wall from one side.
6) Is the 125KOSG knockout seal steel or plastic?
Steel with a zinc finish, not plastic. That makes it appropriate for metal enclosures and panel boxes where an installer wants the plug to match the box material rather than a snap-in poly plug.
7) Can I buy a single 125KOSG knockout seal or is there a minimum order?
Metallics 125KOSG knock-out seals are sold in a minimum of 10 each, so plan the order in multiples of ten rather than singles. Ten of them run about 0.78 lbs total.
8) Can a knockout seal be installed when I can only reach one side of the panel?
Yes. The Metallics 125KOSG is a quick-seal type: the gasketed plate goes against the opening and the hardware draws it tight, so an unused 1-1/4 inch knockout in a live panel can be closed without pulling the enclosure or getting behind it.
