1)Minimum embedment depths reflect values for ductile steel failure of the anchor in accordance with ACI 318 for 3000 and 6500 PSI concrete, respectively.
(2)Use the lesser strength of the outer or inner stud capacity for anchor structural capacity in design.
(3)For Type C anchor applications, please contact your Williams representative to determine the capacity of the cable hole.
