Load Tables

  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Minimum side cover for full loads is 3" for CBs.
  3. Install with bottom of base flush with concrete.
  4. Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for installations that lack top support (such as fences or unbraced carports).
  5. All references to bolts are for structural-quality through bolts (not lag screws or carriage bolts) equal to
    or better than ASTM A307, Grade A.
