The Simpson PPBF44 Adjustable Porch Post Base from Simpson is engineered to safely support porch framing through all phases of construction, giving contractors a reliable, load-rated connection point for nominal 4x4 posts from the moment framing begins to well after the concrete slab is poured. The adjustable seat threads up or down on the threaded rod to accommodate varying porch-slab thicknesses, allowing builders to set the correct height before the slab is placed and eliminating the need for temporary vertical support at any stage of the project.

Key Features

• Adjustable seat accommodating 4 in. to 12 in. slab thickness - lets contractors install the post base and post at the start of construction and fine-tune the height before the concrete is poured, removing the need to re-work the connection later
• Tested and load rated before and after concrete embedment - supports the weight of most framed porches and overhangs during construction, so the structure is stable and verifiable at every phase
• Eliminates temporary vertical support - saves time and money on the jobsite by streamlining the construction sequence and simplifying subcontractor scheduling
• Fastens with two Titen Turbo concrete screws at the foundation - provides a secure, code-ready attachment to the footing while framing the porch roof, without requiring full concrete encasement first
• 12-gauge seat and 3-gauge base plate construction with galvanized and Simpson Strong-Tie gray paint finish - delivers the material strength and corrosion resistance expected of a structural post base used in outdoor porch applications
• Improves jobsite safety for installers and inspectors - by providing a rigid, rated connection point early in the build, workers and inspectors can operate safely on and around the porch roof structure without relying on makeshift supports

Why This Product

• One installation, no rework - the seat's full range of height adjustability means the post base and post can be set correctly before the slab is poured, eliminating costly repositioning and keeping the project on schedule
• Rated for real-world porch loads at every stage - because the PPBF44 is tested and load rated both before and after concrete embedment, contractors and inspectors have documented load values to work with throughout the entire construction process, not just at completion
• Reduces labor costs by cutting out temporary supports - by safely carrying porch framing loads from initial installation forward, this post base removes a time-consuming and expensive temporary-support step that is common on porch roof projects
• Built for demanding outdoor structural use - the heavy-duty base plate, threaded rod, and dual-finish protection make this porch post base a dependable long-term anchor for covered porches, overhangs, and similar framed outdoor structures

Frequently Asked Questions

What is the height adjustment range of the PPBF44 porch post base?

The PPBF44 seat adjusts to accommodate varying porch-slab thicknesses from a minimum of 4 in. to a maximum of 12 in. The height is adjusted by threading the seat up or down onto the threaded rod, allowing contractors to set the correct height before the porch concrete slab is poured.

How is the PPBF44 fastened during installation?

The PPBF44 fastens to the footing with two 3/16 in. x 1-3/4 in. Titen Turbo concrete screws in the foundation when framing the porch roof, and is secured to the post using (12) 0.148 in. x 1-1/2 in. nails.

Does the PPBF44 support porch framing before the concrete slab is poured?

Yes. The PPBF44 is tested and load rated to support the weight of most framed porches and overhangs before the post base is embedded in concrete. Load values are also provided for after the base has been embedded in concrete.

What post size is the PPBF44 designed to fit?

The PPBF44 is designed for a nominal 4x4 post size. The seat is 12 gauge, the base plate is 3 gauge, and the threaded rod is 3/4 in. in diameter.
