1 The minimum distance to hollow head joint is measured from the center of an anchor to the centerline of a hollow head joint( vertical mortar joint). 2 The minimum end distance from the center of an anchor to the end of the top of the CMU wall is 4 inches. Edge and end distances are illustrated in Figure 2.
