Whether you're a DIY enthusiast, a craftsman, or a business professional managing construction projects, selecting the right post base is a crucial step in ensuring both the structural integrity and aesthetic appeal of your project. With so many options available, it can initially feel overwhelming to make the correct decision. That’s why we’ve created this comprehensive guide to help you understand post bases and how to order the perfect one for your needs.
By the end of this blog, you’ll better understand what a post base is, its uses, the various types and considerations for selecting the right one, and even instructions for installing them. 
What Is a Post Base?
A post base is a fundamental structural component used in buildings, fencing, and other construction projects to ensure the stability of vertical posts or beams. This hardware, usually made of metal, anchors the post securely to a foundation, such as concrete or wood, while adding to the durability and longevity of the structure.
Post bases also come in different designs—some purely functional and others adding decorative flair—allowing for versatility in style and construction needs. 
What Are Post Bases Used For?
Post bases are primarily designed to enhance the durability of structures, ensuring they remain steadfast over time. By securely attaching posts to underlying concrete or wooden foundations, they reduce the risks of movement, tilting, and structural issues.
They are commonly used for:
- Building decks
- Installing fences
- Securing pergolas
- Setting up mailboxes
- Constructing gazebos, carports, or porches
Whether you're focused on functionality, style, or both, choosing the right type of post base is essential.
Choosing a Type of Post Base
Not all post bases are designed the same, and your choice depends heavily on your specific application. Here are the primary types you’ll encounter: 
Flush Mount Post Base for Existing Concrete or Wood
Do you already have a concrete foundation in place? A flush mount post base is your go-to. These bases are designed to sit flat on the surface, creating a sturdy connection directly to the existing concrete. They’re practical and ideal for decks, fences, or posts that will not require digging into the foundation.
Tip: Ensure the concrete is level and clean to avoid instability or improper fitting. 
J Hook Post Base for Pour-in-Place Applications
For pour-in-place applications, J hook post bases are the ideal choice. These are set in freshly poured concrete, offering a stronger and more permanent bond between the post and the foundation. Since the post base is secured while the concrete is curing, this method is recommended for projects that demand maximum stability, such as retaining walls and heavy structures.
Tip: Coordinate the placement of the J-hook base during the pour to ensure alignment with your post. 
Faux Post Base for Decorative Use
Sometimes, functionality isn’t everything. If your post has already been installed and you’re looking to enhance its appearance, a faux post base is purely decorative and doesn’t offer structural support. Perfect for design-conscious projects, these add that finishing touch to posts for a more modern, rustic, or customized look.
Tip: Use faux post bases to match the decorative theme of your space effortlessly.
Choosing a Size
Getting the size of your post base right is vital—too small or too large, and your post won't fit securely. Old West Iron simplifies this by crafting post bases to your post's exact dimensions. Here’s how to ensure the correct fit:
- Measure Precisely: Use a measuring tape to confirm the actual dimensions of your post. Don’t rely on nominal sizes, as they often differ based on the mill. For example, a "4 x 4" post might measure closer to 3 ½” x 3 ½”.
- Provide Exact Dimensions: When ordering, always list the exact measurements you recorded, rather than the nominal lumber size, to avoid fitting issues.
Tip: Always double-check your measurements before placing an order to ensure a proper fit. 
Do I Need a 1-Inch Standoff?
A 1" standoff might not always be necessary, but there are certain circumstances where it’s highly recommended—or preferred for aesthetic reasons:
- When to Use It Structurally: If your post will be installed in areas prone to standing water, a 1" standoff elevates the post above the ground, protecting it from moisture and potential rot.
- For Style Preferences: Even if water isn’t an issue, a standoff creates a bulkier and more pronounced look, often preferred for decorative purposes.
Pro Tip: If you're uncertain, opting for a standoff is usually a safe choice for added protection and design versatility.
Hole Options
When ordering a post base, you’ll need to know the difference between two types of holes:
Base Plate Holes
These are located in the base plate that sits under your post. They are used to attach the post base to concrete or other foundation materials securely. Always ensure the holes align with your foundation's anchor points.
Connector Holes
These are visible on the post base's vertical straps and are used to secure the post itself to the base. They are critical for stability and completing the assembly.
When ordering your post base, double-check how many base plate and connector holes you’ll need for your project, keeping in mind both practical and aesthetic considerations.
How to Install Post Bases
Installing a J Hook Post Base
- Set the J hook post base into wet concrete before it hardens.
- Ensure proper alignment by using a level and positioning the post where needed.
- Allow the concrete to cure fully, generally 24-48 hours.
- Finish by attaching the post to the secured base with screws or bolts.
Installing a Flush Mount Post Base
- Clean and level the existing concrete surface.
- Position the flush mount base on the desired spot.
- Drill pilot holes into the concrete using the base plate holes as a guide.
- Secure the base with anchor bolts or screws.
- Attach your post to the secured base.
Installing a Faux Post Base
- Line up the "ears" of your faux post base at the bottom of your pre-installed post.
- Adjust for alignment and aesthetic position.
- Secure the base using decorative screws or hardware if desired. We recommend our clavos for faux post bases as an added touch of decorative charm.
- Enjoy the decorative enhancement to your post!

Frequently Asked Questions
What is a Post Base?
A: A post base is a structural piece used to connect a post to the ground, usually on a cement foundation or patio.
How do Post Bases Work?
A: Post bases are secured to the ground either using a J hook placed before the foundation or lag screws installed into pre-drilled holes in the foundation. A post is then set into the post base between the "ears" and is secured with fasteners like lags or bolts.
What is a 1" Standoff?
A: The 1" standoff option refers to an optional 1" rim around the bottom of your post base that helps to elevate the post 1" off of the ground. If your posts are already elevated or you live in an area that doesn't experience flooding and heavy rainfall, you probably don't need a 1" standoff. If your property does experience flooding, a 1" standoff is an important part of your structure, elevating your wooden post to prevent the wood from becoming waterlogged and rotten.
