Supplier of blanking plugs

[polo1]

Hi folks, anyone know of a supplier of blanking plugs for Lucy/Henley blocks - for use where the break out.....has been broken out and no longer has a conductor in place.
Yes, I know I could dob in some silicon, but I prefer the real thing!
TIA

what about that brown sealant stuff i forget the name of, but an older sparky i worked with used it to seal up holes on a metal db, i think it may have been a type of resin but not sure

Cheers D, not sure why these didn’t come up in my web search. They would probably do the trick, but pricy for what they are!!!!!
