Country of Origin: United States Approved Applications Deck post-to-concrete connections Patio cover post or column bases Other top-supported structural post installations Frequently Asked Questions What size post is the PB46 designed for? The PB46 is designed for a nominal 4x6 post or column size. How is the PB46 installed in concrete? The PB46 embeds in wet concrete after the pour and is made to install flush with the concrete surface. It is installed with 16d common nails to secure the post to the base. What type of corrosion protection does the PB46 have? The PB46 features a G90 zinc galvanized coating, providing extra corrosion resistance that makes it well suited for outdoor and treated-wood applications. Is the PB46 suitable for use in fences or unbraced carports? No. Post bases in the PB series do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations such as fences or unbraced carports. They are intended for decks, patio covers, and other top-supported structures. Note: Product dimensions and/or screw or bolt holes may differ from picture.
