I don't understand your question but let me see if i can answer, the drain is a 1 1/4 and they also list it as 1 1/2" inches, just make sure you order the oil rubbed bronze or antique copper finish, this copper sink once is under mounted, you don't see the flange that reduces the size of the cut out 2", this sink can be mounted on a counter that is 18 inches deep as minimum so any thing bigger you should be fine,

i hope it answers your question if not please contact me as many times as necessary,

thanks for your interest, in our sinks

Thanks, I just wanted to make sure that the cabinet base would be big enough. I have a 21" cabinet.
