See the load values.
  1. Allowable loads have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  2. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the tables reflect installation into the wide face. See technical bulletin T-SCLCOLUMN for values on the narrow face (edge).
  3. Base allowable loads assumes nails have full penetration into supporting member. Loads do not apply to end grain post installations.
  4. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long. See other nail sizes and information.

The BCS allows for the connection of 2-2x's to a 4x post or 3-2x's to a 6x post. Double-shear nailing between beam and post gives added strength! The BC series offers dual purpose post cap/base for light cap or base connections.

Material: 18 gauge

Finish: Galvanized. Some products available in ZMAX® coating and stainless steel; see Corrosion Information.


  • Use all specified fasteners. See General Notes.
  • 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 16dx2 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.
