Frequently Asked Questions

What type of concrete installation is the PB66Z designed for?
The PB66Z is designed to embed in wet concrete after the pour and is made to install flush with the concrete surface, creating a clean and secure connection at the base of a 6x6 post or column.
Why is ZMAX galvanization important for this post base?
ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications, making the PB66Z especially well-suited for outdoor environments such as decks and patio covers where moisture and treated lumber can accelerate corrosion in standard hardware.
What fasteners are used to install the PB66Z?
The PB66Z is installed with 16d common nails or 1/2 in. diameter bolts, providing flexible fastening options depending on the specific requirements of your project.
Is the PB66Z suitable for non-top-supported structures like 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 therefore are not recommended for non-top-supported installations such as fences or unbraced carports. The PB66Z is intended for top-supported structures such as decks and patio covers.
