Does anyone have a good single gang box with at least 2-3/4" holes in the top/bottom that'll work well in block walls? Right now we're using 3.5" deep boxes but the ko closest to the front puts the pipe in the web of the block. I need something with the ko spaced at least an 1.5"+ back from the front to clear the web. The masonry blocks they're using right now are fairly deep, probably around 11 inches, so I've got plenty of room for a deeper box. We're using Steel City boxes, it looks like Raco makes about the same thing too.

They must make something for this....

We always use a 4 11/16" box with a 2" raised cover. The 2" allows the box to fit nicely into the void of the block and is deep enough to get the front of the cover flush.

That's the same as I use.
Works very well.
