PPBF Post Base

PPBF

On This Page

The PPBF adjustable porch post base safely supports porch framing through all phases of construction, eliminating the need for temporary vertical support and providing a stronger structure for contractors working on and around the porch roof. The seat adjusts to accommodate varying porch-slab thicknesses from 4" to 12", providing contractors with one-time installation of the post base and post at the beginning of construction. This adjustability gives contractors the option to set the post base at the correct height before the porch concrete slab is poured.

The PPBF fastens to the footing with two Titen Turbo™ concrete screws when framing the porch roof. The height of the post base can be adjusted by threading the seat up or down onto the threaded rod. The PPBF is tested and load rated to support the weight of most framed porches and overhangs before the post base is embedded in concrete. The table also provides load values for the base after it has been embedded in concrete.

Key Features

  • Makes the jobsite safer for installers and inspectors
  • Allows builders to attach the post framing and post base to the foundation before the porch slab is poured with minimum 4” and maximum 12” height adjustability
  • Saves time and money by eliminating the need for temporary supports and streamlines the subcontractor scheduling process
  • Available in two sizes to accommodate nominal 4x4 and nominal 6x6 posts.

Material

  • Seat: 12 gauge
  • Base plate: 3 gauge
  • Threaded rod: 3/4 in. diameter

Finish

  • Simpson Strong-Tie gray paint

Installation

  • Use all specified fasteners; see General Notes.
  • Locate and place the PPBF on the foundation according to the framing plans. Secure the PPBF to the footing with (2) 3/16"-diameter x 1 3/4"-long Titen Turbo hex-head screw anchors located a minimum of 1 1/2" from the edge of the concrete.
  • Adjust the seat height according to the post length specified in the framing plans, with consideration given for the porch slab thickness and standoff (1" minimum to 2 1/2" maximum). Drill a maximum 7/8"-diameter hole into the bottom of the post if necessary, or cut all-thread rod flush to the post base seat.
  • Attach a wood post to the PPBF using (12) 0.148" x 1 1/2" nails. After the top and bottom of the post have been braced against lateral movement, the post may then be loaded in download or uplift.
  • When ready, pour the concrete porch slab up to 1" from the bottom of the seat of the post base.
