A saddle lifts a conduit run over an obstruction and returns it to the same line. The common three-point saddle uses a 45-degree center bend over the obstruction and a 22.5-degree bend on each side; the outer marks sit 2.5 inches from the center for every inch of obstruction height, and the center mark moves 3/16 inch forward per inch to allow for shrink. Wider obstructions call for a four-point saddle.
Two-inch water line across the wall, put a three-point saddle in it, marks at five inches each side of center.
