Frequently Asked Questions
- What size post is the PBST44Z designed to fit?
- The PBST44Z is specifically designed for use with 4x4 nominal lumber posts, making it ideal for standard deck, porch, and patio cover post applications.
- Why is the 1 in. standoff between the post and concrete important?
- The 1 in. standoff helps protect the base of the wood post from direct contact with moisture that can accumulate on concrete surfaces, reducing the risk of moisture-related rot. This standoff distance also meets applicable code requirements for post base installations.

- The PBST44Z offers installation flexibility and is compatible with (14) 0.162 in. x 3-1/2 in. nails, (14) #10 x 1-1/2 in. Strong-Drive SD Connector screws (SD10112), or (2) 1/2 in. diameter bolts.
- What makes the ZMAX coating suitable for outdoor use?
- The ZMAX galvanized coating provides a thicker zinc layer than standard G90 galvanizing, offering superior corrosion resistance for post bases exposed to weather and outdoor conditions - making it well-suited for decks, patio covers, porches, and similar exterior structures.
