Load Tables

  1. Allowable loads have been increased 60% 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 non top–supported installations (such as fences or unbraced carports).
