The Simpson Strong-Tie PB44 Non-Standoff Post Base is a cast-in-place post base for securing a nominal 4x4 wood post or column to concrete or masonry. This is a post base designed for fastening wood-to-concrete or masonry in top-supported structures. Model Number PB44. If you are building a deck, patio cover, or similar structure and need the post tied directly into a fresh concrete pour, this connector gives you a simple engineered way to do it.

What matters here is how the PB44 is meant to be installed. It embeds in wet concrete after the pour and sits flush with the concrete surface, so the base becomes part of the connection instead of relying on a separate anchor added later. For new work, that can save steps and keep the connection layout clean. The non-standoff design also keeps the post seated low in the base, which is useful when you want a direct post-to-foundation connection for supported structures.

Simpson builds the PB44 from 12-gauge steel with a zinc galvanized G90 finish. The heavy steel body is paired with an embossed seat for added strength, and the stress-relief holes under the base are there to help resist tearing during loading. Those are not throwaway details. They are the kind of small design choices that matter in a connector because the load path runs right through the base and into the concrete.

In practical use, the PB44 is sized for nominal 4x4 posts, with a width of 3-9/16 inches and a length of 3-1/4 inches from the published model table. Installation uses nails on this model, specifically 0.162 inch by 3-1/2 inch nails. That gives you a clear fastener path and a defined install method instead of field-guessing what should go where. As always with structural connectors, using the specified fasteners matters because that is how the listed performance is achieved.

This connector is intended for decks, patio covers, and other top-supported structures. That last part is important. Simpson specifically notes that PB post bases do not provide adequate resistance to prevent members from rotating about the base, so they are not recommended for non-top-supported installations such as fences or unbraced carports. In other words, this is a solid choice when the structure above helps brace the post, and the wrong choice when the post must resist rotation on its own.

Jobsite practicality is straightforward. The PB44 is a single-piece connector with a packaging quantity of one, so it is easy to stage and place before or during the pour. The galvanized finish helps with basic corrosion resistance in the right environment, but the standard PB44 is listed as G90 galvanized and is not the treated-lumber version. If your project calls for different corrosion protection, Simpson does offer other coatings in the PB family, but this specific model is the standard zinc galvanized version.

Who should buy it? Carpenters, deck builders, remodelers, and general contractors doing new concrete work for wood posts. If you need a 4x4 post base for a fresh pour and your application is a properly top-supported structure, the PB44 is the right kind of hardware: simple, specific, and engineered for the job. If you need a stand-off to lift the post above the concrete or you are working on an unbraced post application, you should be looking at a different base instead.

Simpson Strong-Tie PB44 Non-Standoff Post Base Keeps New Post Work Simple

If you are setting 4x4 posts into a fresh concrete pour for a supported structure, this is the kind of connector that does exactly what it is supposed to do without a lot of drama.

• Who it's for: Deck builders, carpenters, and contractors installing nominal 4x4 posts for patio covers, decks, and similar top-supported framing.
• Why it stands out: The 12-gauge build, embossed seat, and cast-in-place design give you a purpose-built connection instead of a generic bracket trying to do too much.
• Worth knowing: This is a non-standoff base, and Simpson does not recommend PB post bases for non-top-supported installs like fences or unbraced carports. Use it where it belongs and it is a solid choice.

• What size post does the PB44 fit? It is designed for a nominal 4x4 post or column.
• Is this post base installed in wet concrete or hardened concrete? The PB44 is a cast-in-place model that embeds in wet concrete after the pour.
• Can the PB44 be used for a fence post? Simpson states that PB post bases do not provide adequate resistance to prevent rotation about the base, so they are not recommended for non-top-supported installations such as fences.
• What fasteners does this model use? The PB44 uses 0.162 inch x 3-1/2 inch nails.
