Description reads “topmount” but the XLU denotes an undermount sink.
Which is it?
Thanks!
Good question. It’s an undermount. we’re correcting the title.
Thanks!
Now if only I could find the dimension of the drain hole…
The Houzer page has downloads for specs, template, and installation.

It seems like you are my personal shopping assistant. 
I found those earlier, but the template file is a dxf.
I dont really feel like going to the trouble to find a compatible piece of software to open it. AutoCAD offers a free trial, but blah blah blah…toooooo much trouble.
I would assume its a standard 3.5" opening, but the strainer pages show a 2" as an option.
