The Simpson PB44R 4x4 Rough Cut Galvanized Post Base is a structural connector from Simpson engineered to create a secure, load-bearing connection between a rough cut 4x4 post and a concrete or structural footing. Built for top-supported applications such as deck post-to-footing connections, patio cover post bases, and outdoor structural columns, this post base pairs durable steel construction with a corrosion-resistant finish to deliver dependable performance in demanding outdoor environments and with pressure-treated lumber.

Key Features

• Sized specifically for 4x4 rough cut posts - ensures a proper, snug fit with rough cut lumber so the connection is structurally sound right from installation, with no guesswork about compatibility.
• Zinc Galvanized G90 coating - provides reliable corrosion resistance suited for outdoor use and direct contact with pressure-treated wood, helping the connector hold up against moisture and the elements over time.
• 12-gauge steel construction - delivers the structural strength needed for load-bearing post-to-base connections on decks, patio covers, and similar top-supported structures.
• Engineered for top-supported installations - correctly matches the application type where post bases perform best, reducing the risk of improper use and helping ensure code-compliant deck and patio builds.
• Made in the United States - domestic production supports consistent quality standards for a structural connector where reliability matters.

Why This Product

• Purpose-built fit for rough cut lumber - unlike post bases sized for dressed lumber, the PB44R is specifically designed around rough cut 4x4 dimensions, so builders and DIYers working with rough cut stock get a connector that actually fits correctly without shimming or workarounds.
• Corrosion resistance where it counts - the Zinc Galvanized G90 coating makes this post base a practical choice for outdoor deck and patio projects where moisture exposure and pressure-treated wood chemicals can quickly degrade unprotected steel hardware.
• Straightforward installation for structural applications - the PB44R is engineered for common top-supported structures like deck post-to-footing connections and patio cover bases, giving contractors and homeowners a connector that fits clearly defined, widely used applications without overcomplicating the build process.
• Consistent quality from a trusted structural connector brand - produced in the United States by Simpson, a recognized name in structural connectors, this post base is designed to meet the demands of real-world outdoor construction projects.

Frequently Asked Questions

What post size is the PB44R designed for?

The PB44R is specifically designed to fit a 4x4 rough cut post, providing a proper structural connection between the post and its base.

Can the PB44R be used for fences or unbraced carports?

No. Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations such as fences or unbraced carports.

What fasteners are required to install the PB44R?

The PB44R installs using 0.162" x 3-1/2" nails. A 2" minimum side cover is also required to obtain the full rated load.

What type of galvanization does the PB44R have, and is it suitable for treated wood?

The PB44R features a Zinc Galvanized G90 coating, which provides corrosion resistance well-suited for outdoor applications and use with pressure-treated wood.
