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 BC series offers dual purpose post cap/base for light cap or base applications.

  • 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
  • Z-MAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Install with 16d common nails or #10 x 1-1/2 in. Strong-Drive SD screws

Rated 4.2 out of 5 by 12 reviewers.
Rated 2.0 out of 5.0 by Poor choice, had to get stonger base. No strength, wobbly, not strong enough to do the job. December 30, 2014
Rated 3.0 out of 5.0 by Well made, Well Sized I use these to fasten 4x4s to concrete patios, and they work well. I just wish all these galvanized products weren't so bloody expensive. We need more competition here, guys, to keep you honest! April 8, 2014
Rated 4.0 out of 5.0 by Galvanized 4x half base product was just what I needed to support the new hand rail. October 28, 2014
Rated 5.0 out of 5.0 by Works well I used this bracket for a 4x4 post installation. I actually didn't use it as a base, but used it to hold the top of the post. Holes are drilled, so it was easy to install. Galvanized, so it shouldn't rust. October 15, 2014
Rated 5.0 out of 5.0 by Made in the USA Simpson is the leader in this field, and they manufacture their products in the USA. Check out their website for an exhaustive product line to solve your connection problems. I am tired of getting stung with inferior products manufactured overseas (aka China) and I will pay a little bit more to support domestic manufacturing AND a superior product. June 24, 2014
