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.

I believe the op is talking about this type of floor box cover.

Can you take a pic of the existing box?

"Device box" made me envision 1G rectangular.

Handy Box?

Thank you all for your reply
It's a mud box single gang in the floor. I would transition from the single gang plate to mc

Would a single gang stainless steel plate with 7/8 hole be listed for a floor penetration?

If it’s that type of box, you might consider a bell box blank with gasket, though the stainless would be sturdier.
