Meyers Hub?

[mtfallsmikey]

I've purchased stainless locking Myers Hubs for the water heating elements for my cooling towers...the water treatment chemicals eat up the pot metal ones. Me thinks they were around $100/ea.

If meter base KO has the raised ring mentioned earlier, neither a sealing locknut or a Myers hub will fit and seal well. The meter base hub is the correct thing to use. With a flat KO, any of the 3 will work.
