Thomas & Betts PLG-1-RD – Frequently Asked Questions
1) What trade sizes does the Thomas & Betts PLG-RD round plug come in?
Three trade sizes: 1/2 inch (PLG-1-RD), 3/4 inch (PLG-2-RD) and 1 inch (PLG-3-RD). Match the plug to the trade size of the open knockout or hub you are closing off, not to the conductor size.
2) Are Thomas & Betts PLG-RD plugs sold individually or in a box?
The unit of measure is each, but orders go in multiples of 100 and the outer pack is 100 pieces. So a job needing a handful still buys a hundred-count box, which is normally how an electrical contractor stocks closure plugs anyway.
3) What is the PLG-RD plug made of, and will it hold up in a damp or corrosive area?
It is a zinc plug with a silver finish. Zinc gives you a metal closure that suits metallic boxes and conduit bodies rather than a plastic snap-in cap, though nothing in the specs designates it for wet or classified locations, so treat it as a general-purpose metallic closure.
4) Does the Thomas & Betts round plug have a knockout in it?
No. The PLG-RD is solid, with no knockout, so it is a permanent closure for an unused opening. If you need the ability to open the hole later for a future run, a knockout seal is not what this is.
5) Are these plugs RoHS compliant for an institutional or government spec job?
Yes, the PLG-RD zinc round plugs are RoHS compliant, which is usually the box that has to be ticked on public and healthcare procurement submittals for small electrical hardware.
