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 2-2x's to a 4x post or 3-2x's 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)
  • Made from 18-Gauge steel
  • ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Install with 10d common nails or #9 x 1-1/2 in. Strong-Drive SD screws

Rated 5.0 out of 5.0 by Post caps used for 38 ft beams. First time to ever use Simpson post fasteners. Good experience. Post caps really helped plumb the beams. Still need to block between beams but caps are definitely the way to go. September 30, 2014
