10×10 Post Base for Concrete Heavy Duty Adjustable Post Bracket with 1.2″ Standoff

The EONECROSS 10×10 post base provides a sturdy connection between 10×10 wood posts and concrete surfaces. Made from 2mm thick steel, this heavy-duty post base supports pergolas, decks, patios, gazebos, porches, and other outdoor structures. The base fits posts with an actual 9.5″ x 9.5″ size and keeps the wood elevated above the ground to help reduce moisture exposure.

A corrosion-resistant e-coating and galvanized protection help the 10×10 post base withstand outdoor conditions. Pre-drilled mounting points and included self-tapping and expansion screws make installation more straightforward on suitable concrete surfaces.

Key Features

Heavy-Duty 2mm Steel Construction

The 10×10 post base uses 2mm thick steel to provide firm support for compatible wood posts. The reinforced structure helps keep the post connection stable during normal outdoor use.

Fits 9.5″ x 9.5″ Wood Posts

Although designed for standard 10×10 lumber, the actual inner dimensions are approximately 9.5″ x 9.5″. Measure your post before ordering to confirm compatibility.

Ground Standoff Helps Protect Wood

The elevated design keeps the bottom of the wood post above the concrete surface. This separation helps reduce direct contact with moisture and can help extend the service life of the post.

Corrosion-Resistant Surface

The steel body features protective surface treatments designed to help resist rust and corrosion during outdoor use.

Hardware Included

Each package includes the post base, expansion anchors, self-tapping screws, and installation instructions.

10×10 Post Base for Concrete

The EONECROSS 10×10 post base is designed for projects where a wood post needs to connect to a concrete surface.

The base creates a physical separation between the bottom of the post and the concrete. This design can help reduce direct moisture exposure around the bottom of the wood.

It works well for outdoor projects such as:

• Pergolas
• Decks
• Patios
• Gazebos
• Porches
• Outdoor shade structures
• Other suitable wood-frame projects

Before installation, verify the post dimensions and concrete condition for your specific project.

Fits 10×10 Wood Posts

This 10×10 post base is designed for standard nominal 10×10 lumber with an actual post size of approximately 9.5″ x 9.5″.

This distinction is important because nominal lumber dimensions do not always match the actual measured size.

Recommended copy:

Always measure your actual post before installation. A nominal 10×10 wood post may have different finished dimensions depending on the lumber and finishing process.

If you are working with smaller posts, our 6×6 post base is another option for common wood post applications.

Heavy-Duty Steel Construction

The 10×10 post base uses 2mm thick steel for a strong and durable structure.

The steel construction provides firm support around the bottom of the wood post. The design is suitable for outdoor construction projects where a stable connection between wood and concrete is required.

The protective coating helps the steel handle normal outdoor exposure and reduces the risk of surface rust and wear.

Ground Standoff Design for Better Post Protection

One of the key features of this 10×10 post base is the elevated post position.

The base keeps the wood post above the concrete rather than placing the bottom of the post directly against the surface.

This separation can help:

• Reduce direct moisture contact
• Improve airflow around the post bottom
• Reduce moisture-related wood deterioration
• Create a cleaner post-to-concrete connection

10×10 Pergola Post Base Applications

The EONECROSS post base works well for outdoor projects that use compatible 10×10 wood posts.

Pergolas

Use the post base to create an elevated connection between pergola posts and suitable concrete surfaces. For pergola projects, you can also combine the post base with 4×4 pergola brackets to create a more complete post connection system.

Decks

The elevated design can help keep compatible deck posts separated from the concrete.

Patios and Gazebos

The bracket can also work for suitable patio covers, gazebos, and outdoor structures.

Porches

For porch construction, verify the lumber dimensions and mounting requirements before installation.

Easy Installation

The 10×10 post base for concrete includes mounting hardware to simplify installation.

Basic installation process:

1. Measure the post

Confirm that the wood post measures approximately 9.5″ x 9.5″.

2. Position the post base

Place the base where the post will be installed.

3. Mark the mounting points

Use the pre-drilled holes to mark the appropriate locations.

4. Prepare the concrete
