Find your controller box and locate its mounting holes on the back.
Place it on top of the 6x15 plate so it is square and the top hole is about ½” away from the top. Transfer punch the holes on the controller box to the plate.
Drill those 1/4" holes.
You can drill them a little bigger (up to 5/16") if you'd like, as it's difficult to get the holes perfectly aligned.
Punch the holes in the bottom piece.
