Product Overview

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 PBS series provides a connection between a post (or column) for decks, patio covers and other top-supported structures.

  • Embeds in wet concrete after pour and is made to install flush with the concrete surface
  • Embossment in the seat of the base gives increased strength
  • Stress relief holes under the base resist tearing during loading
  • Features a 1 in. standoff height, reducing the potential for decay at post and column ends
  • Nominal post size: 4 in. x 4 in.
  • Made from 12-Gauge steel base; 14-Gauge steel strap
  • ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Install with 16d common nails, #10 x 1-1/2 in. Strong-Drive SD screws or 1/2 in. Dia machine bolts

Customer Questions & Answers

how do you properly install this structure? PBA44AZ Simpson Tie

While i know you put in the concrete do you put rebar through the holes on the underside that will be in the cement. Do you need to run a vertical rod as well? What is reccomeded to go through post on the top side? A nut and bolt or a set of screws. Will it support the Gates corner post? Thank you.
Asked by: Anonymous
The concrete design is per the Designer/Engineer of Record, but the holes in the bottom are to allow for free concrete flow (rebar not required here). Nails (16d common) or 1/2" diameter through bolts are to be used for post attachment; please see the following link for the allowable loads (second table) based on which fasteners are used: http://www.strongtie.com/products/connectors/pb-pbs.asp#tables. It is up to the Designer/EofR to specify the appropriate connector based on the application (framing layout, demand loads, local building codes, etc.), but I can tell you we do not have any bases recommonded for non top-supported installations (i.e. fences, unbraced carports, etc.) Thank you!

Rated 5 out of 5 by from a strong foundation After building a very solid deck my wife and i decided to make an equally solid playstructure for the kids. Deck blocks only get it so solid- to support the uprights holding the slide I chose Simpson Strong Ties to lock it down. This standoff base was the obvious choice for a couple reasons: 1 the anchor base is robust and sits securely in the concrete. 2 the standoff plate keeps the wood off the ground and dry. 3 the nailing plates are long. This gives them more contact to prevent twisting of the posts. Connected with 1" Z-max 10p nails.

Rated 5 out of 5 by from Best Fence post bracket on the market!!! The Simpson fence post bracket is unbelievably strong and of the highest quality. When the fence post is attached to this support it is there to stay permanently!!!!

Rated 5 out of 5 by from Must for my deck! I was looking for a product that would provide strong lateral support for 4x4 posts (approx 8' tall) that would be supporting fence panels on a deck. After searching online and at various hardware stores, these appeared to seat in the concrete the deepest and also have the highest bracing for the posts. See my attached pic for the final product. I was very pleased!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Simpson Ties As usual, Simpson makes excellent braces. I strongly recommend using earthquake straps where and when needed.
