Openings up to six feet wide require two number five bars, openings up to eight feet wide require two number six bars, and openings up to sixteen feet wide require three number six bars unless noted otherwise. Wall jambs require two number five bars for openings up to twelve feet wide and four number five bars for openings up to sixteen feet wide. Minimum clearance is maintained at one inch or bar diameter, whichever is greater, with a second row of bars provided where applicable.
