These drip trays set into the counter top. The dimensions given below are the cutout size you need. The flange (or lip) around all four sides is 3/8-inch. All of these trays have a drain hole and come with a drain fitting. All you need to do is attach a piece of hose to it.
DIMENSION MAY VARY +/- 1/16”. DO NOT MAKE ANY CUTS IN YOUR COUNTER TOP UNTIL THE TRAY IS IN HAND.
Now that we got your attention, here’s the reason behind the red type: Due to the variables in sheet metal and the bending process used to form these trays there can be about a 1/16” variation in length and width. Be patient, wait for your tray to arrive and use it as a template for any cuts you need to make.
