Prevent Corrosion

Post and column bases secure the bottom of posts or columns to concrete and are perfect for decks or patio covers. Models are available for attaching to existing hardened concrete, wet concrete, as well as wood. The BCS allows for the connection of 2-2xs to a 4x post or 3-2xs to a 6x post. Double-shear nailing between beam and post gives added strength.
  • Provides a positive connection for a post to a wood deck
  • Stronger than angled nailing or screw fastening
  • Reduces the chance of the post splitting and eliminates nailing into end grain
  • Not recommended for non top-supported installations (such as fences or unbraced carports)
  • Nominal size: Double 3x beam, 6x post
  • Made from 18-gauge steel
  • Galvanized (G90) for extra corrosion resistance
  • Install with 16d common nails

Questions & Answers


G90 coating is not suitable for treated wood (exterior use). Does BCS2-3/6 come with G185 galvani...

Asked by Birmingham October 6, 2019

Yes you can order these for exterior use also or get galvanized spray paint and coat yourself

Can I use this to attach a double 2x12 beam to 6x6 post

Asked by Jarrett April 30, 2019

The BCS2-3/6 is sized for a triple 2x beam to a 6x post. If shimming out the double 2x to fit the cap, the built-up lumber (multiple members) must be fastened together to act as one unit to resist the applied load (excluding the connector fasteners). This must be determined by the Designer. Thank you!

Can these be installed with 3 inch treated screws since this is going into a treated post and beam ?

Asked by lake December 29, 2014

Depending on the connector being fastened, Simpson has specific fastener this case, Post connection should be made with 6 x SD10112 screws and Beam connection should be made with 4 x SD10112 fasteners.

The base needs to be wider to accommodate gaps between 2x12’s. First beam sat on at an angle. For second beam had to clamp them on first to make strait
