The Simpson PPB66-6Z PPBZ Porch Post Base by Simpson is engineered for a simplified, one-time installation that supports permanent porch framing throughout all stages of construction. Sized to fit a nominal 6x6 post and a 6 in. slab thickness, this connector fastens to the footing before the concrete is poured, eliminating the need for temporary vertical support and enabling full access for installers and inspectors without disrupting the construction schedule. Built from 12-gauge steel with a ZMAX galvanized finish, it is purpose-built for exterior porch framing applications where durability and corrosion resistance are essential.

Key Features

• Stiffened embedded side stirrups provide temporary vertical download support without being embedded into concrete - the post and connector stay secure during construction without locking the stirrups into the slab, keeping the concrete pour simple and unobstructed.
• 1 in. standoff at the post base - keeps the post or column end elevated above the slab surface, reducing the potential for moisture contact and wood decay over time.
• Pre-pour installation design - the connector is set and fastened before the slab is poured, eliminating temporary vertical support structures and removing the need for the framer to return to the jobsite after the concrete hardens.
• No disruption to subcontractor scheduling - trades can complete their work in sequence without waiting on or working around temporary shoring, reducing coordination delays on the jobsite.
• Eliminates additional move-ins by trades and certain inspection call backs - the streamlined installation process reduces repeat site visits, saving time and labor costs across the project.
• Sized to fit a nominal 6x6 post and 6 in. slab - designed specifically for this common porch framing configuration, ensuring a proper fit without modification or guesswork.
• Made from 12-gauge steel - provides the structural strength needed to support the weight of most framed porches and overhangs prior to embedment in concrete.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the heavy-duty coating stands up to outdoor exposure and the chemicals present in pressure-treated lumber, extending the service life of the connection.

Why This Product

• One-time installation from start to finish - because the porch post base is fastened to the footing before the slab is poured and requires no return trip after the concrete hardens, builders eliminate redundant labor and keep the project timeline on track.
• Supports the structure before the concrete is even poured - the stiffened side stirrups are designed to carry the vertical loads of most framed porch roofs and overhangs prior to embedment, so construction can continue safely without temporary shoring systems.
• Built specifically for exterior conditions - the ZMAX galvanized finish delivers enhanced protection against moisture and the corrosive chemicals found in treated wood, making this connector a dependable long-term choice for covered porch and column base applications.
• Reduces jobsite coordination complexity - by eliminating temporary vertical support and the scheduling conflicts that come with it, this porch post base allows concrete contractors and framers to complete their respective phases independently, with fewer inspection callbacks and fewer move-ins overall.

Frequently Asked Questions

How is the PPB66-6Z installed before the concrete slab is poured?

The porch post base is fastened to the footing with two Simpson Strong-Tie Titen Turbo masonry screws when framing the porch roof. This pre-pour installation holds the connector and post securely in place, so the concrete contractor can complete the slab pour at a later stage without any interference from temporary vertical support structures.

Does the PPB66-6Z require the framer to return to the jobsite after the slab has hardened?

No. Because the PPBZ is designed for a one-time, pre-pour installation, the framer does not need to return to the jobsite after the concrete slab has hardened. This eliminates additional move-ins by trades and reduces the likelihood of certain inspection call backs.

What corrosion resistance does the ZMAX coating provide?

The ZMAX galvanization offers extra corrosion resistance specifically suited for exterior and treated-wood applications, making the PPB66-6Z well-suited for outdoor porch framing environments where exposure to moisture and the chemicals found in treated lumber are concerns.

What size post and slab thickness is the PPB66-6Z designed to accommodate?

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