Critical information! You must tell your counter top fabricator that the cut out on our sinks should be FLUSH with the inside of the bowl. Your Signature Series or NexGen™ accessories will NOT fit if there is any overhang of the counter top. This is a standard practice, however, some fabricators like to have a small overhang (basically so they don't have to be as accurate when cutting the granite). By the way, a reveal is also an improper installation! Never use silicone when installing a copper sink. Also note: These specific sink designs are Trademarked and copyrighted by Rachiele, LLC.
