Floor box single gang plate for mc connector

[JJWalecka]

I'm looking for a single device floor box blank plate that has a 7/8 hole so I could install a 90 degree mc connector into it

I would appreciate your thoughts

Thank you

What is the brand and model of the floor box? Many floor boxes and their associated parts are listed together.

Most of the manufacturers make a plate that has a threaded center hole, usually in 1”, 3/4” and 1/2” sizes to adapt to a tombstone outlet box. Just go on the manufacturer’s website.
