Frequently Asked Questions

How is the PPB66-4Z porch post base installed prior to the concrete pour?

The porch post base is fastened to the footing using two 1/4 in. x 1-1/4 in. Titen Turbo masonry screws when framing the porch roof. Once secured, the concrete contractor can complete the porch slab pour at a later stage without requiring the framer to return to the jobsite after the slab has hardened.

Does the PPB66-4Z require temporary vertical support during construction?

No. The stiffened embedded side stirrups are designed to provide temporary vertical download support without being embedded into concrete, which means temporary vertical support is not needed. This eliminates disruptions to scheduling and reduces the need for additional trade move-ins.

What corrosion protection does the PPB66-4Z offer for exterior use?

The PPB66-4Z features ZMAX galvanization, which offers extra corrosion resistance specifically suited for exterior and treated-wood applications, making it a durable choice for porch framing exposed to the elements.

What post size and slab thickness is the PPB66-4Z designed for?

The PPB66-4Z is sized to fit a nominal 6x6 post and is designed for use with a 4 in. slab thickness. The 1 in. standoff built into the base also helps reduce the potential for decay at the post or column ends.
