O If a reduction factor value is in a shaded cell,this indicates that this specific edge distance may not be permitted with a certain spacing(or vice versa). Check with table 5 and figure 2 of this section to calculate permissable edge distance,spacing and concrete thickness combinations. KWIK HUS-EZ SCREW ANCHOR-July 2020 9
