Otherwise standard hooks are to be used. 3. Where 'J' is not shown. ''J' will be kept equal to or less than 'H' on truss bars. Where 'J' can exceed 'H' it should be shown. 4. 'H' dimension on stirrups to be shown where necessary to fit within concrete. 5. Where bars are to be bent more accurately than standard bending tolerances, bending dimensions which require closer fabrication should have limits indicated.
