KO plugs

[PoorOwner]

I knocked out the wrong side by mistake, where can I get the kind of plug that has a wing nut and seal?

it is 3/4" thanks

I saw this on amazon but is this something HD sells as well?

Home depot has snap in plugs, if it doesn't have to be weathertight.

Item 322617

The one shown in post #2 is fine, a decent electrical supply house would have what your requesting, but there really is no need for it, unless you had to maintain a NEMA type 4 or 12 rating.

It's also known as a 2 piece knockout seal, which is more well known by that name than a "Type S Knockout Seal with Screw and Bar"
