Post bases and post base anchors are both designed to make installing your posts simple and are essential parts of projects that require securing posts to foundations and surfaces. 

Not sure which one you need? The specific post base or post anchor will depend on your project and it’s always important to consult with the manufacturer’s guidelines.

While they may appear one and the same, and they certainly are very similar, it’s important to understand the ways in which they differ:


  • Ideal for securing a post to a surface
  • Crafted from rigid polyoxymethylene
  • Designed for securing a nominal wood 4″ x 4″ post to any deck or surface
  • Perfect for securing your wood post to a deck or if need a more low-profile option
  • Easy installation process


  • Built from 14 gauge steel
  • Designed for use with nominal 4″ x 4″ posts
  • Perfect for wood or concrete surface mount installations
  • Wide, flare-out design provides added support, a spot for a larger lag bolt and taller area where you insert the post.
  • Easy installation process


Before building a permanent structure, take into consideration where you live and your typical exposure to rain, wind, snow, ice, sunlight, flooding, earthquakes and intense heat. For a safe installation, wear personal protective equipment and use suitable fasteners.

Before construction, check with your local municipality for building code requirements (consulting local building codes is required when supporting permanent structures).

For certain structures, we recommend consulting with a professional to ensure that these products are appropriate for your intended application.
