Description

5" Brass In-floor Drain, Special Setup, Stainless Steel, Brass, Copper.
I have not seen one like this before. Looks like it will drain out using a sphion technique.
Top lid appears to be brass.
Body is stainless steel.
Cup inside appears to be copper.
Looks like you can close it off with the square bolt on top also and stop it from draining.
