The LCB column base helps connect posts to the concrete, with sizes available for 4x4, 4x6 and 6x6 solid sawn posts. The bottom of its base plate is designed to be flush with the concrete.


  • Strap — 12 ga. (97 mil) x 2; base — 16 ga. (54 mil)


  • Galvanized


  • Use all specified fasteners; see General Notes
  • For full loads, minimum side cover required is 2" for LCB
  • Install all models with bottom of base plate flush with concrete
  • 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)


  • LCB is available in rough sizes. Consult Simpson Strong-Tie for bolt sizes and allowable loads.
