If the requirement was 1.5" that would only let us drill a 1/2" hole in a standard 3.5" stud. A 1/2" hole would be worthless for power wiring. With the 1.25" requirement we can drill a 1" hole dead center in a standard stud actually allowing some power wiring to pass through. [ July 10, 2005, 10:17 AM: Message edited by: iwire ]
