I'm calling the specs below "Standard Drainboard". If you write "Standard Drainboard" on the template and paperwork I'll know exactly what to do. If you want something different like just the grooves without a cavity carved out then whatever, get the exact specs and I'll make like standard #1, standard #2, etc.

Also, do NOT sell one of these on Taj Mahal or any materials like that. I won't even try.


If the sink is much less then 15" vertically then this won't work. If it's a farm sink then I'm centering it vertically between the end of the radius and the corner.


This is about 5/16" deep where it meets the sink cutout and about 1/16 deep at the right side. The grooves are about 1/8" deep. I'll snap a photo of a finished one when I remember.
