Simpson Strong-Tie BC4 NER-421 Galvanized Post Cap

Simpson Strong-Tie BC4 NER-421 Galvanized Post Cap

The Simpson Strong-Tie BC4 Post Caps allow you to create a light duty connection between a 4 x 6 nominal post and 4x nominal beam.



  • Use all specified fasteners
  • Do not install bolts into pilot holes
  • BCS — Install dome nails on beam; drive nails at an angle through the beam into the post below to achieve the table loads
  • BC — Install with 16d commons or 16d x 2-1/2" joist hanger nails
  • 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)
  • To tie multiple 2x members together, the Designer must determine the fasteners required to join members to act as one unit without splitting the wood
