BC/BCS Post Caps

BC/BCS

On This Page

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. See Corrosion Information.

Installation

  • 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 0.162" x 3 1/2" nails or  0.162" 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

BC/BCS Post Caps Load Table
  1. Allowable loads have been increased 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 known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions resulting from narrow-face installations.
  3. Base allowable loads assume that nails have full penetration into the supporting member. Loads do not apply to end-grain post installations.
  4. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
