PB/PBS Regular and Standoff Post Bases

The PBS features a 1" standoff height. It reduces the potential for decay at post and column ends.

Material: PB - 12 gauge; PBS - see tables.

Finish: Galvanized. Some products available in ZMAX® or HDG; see Corrosion Information.

Installation:

Use all specified fasteners. See General Notes.
Install either nails or bolts. See General Notes, note d.
Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non top-supported installations (such as fences or unbraced carports).
PB: Holes are provided for installation with either 16d commons or 1/2" bolts for PB66 and PB66R; all other models use 16d commons only. A 2" minimum sidecover is required to obtain the full load.
PBS: Embed into wet concrete up to the bottom of the 1" standoff base plate. A 2" minimum side cover is required to obtain the full load. Holes in the bottom of the straps allow for free concrete flow.

Options: PBS available in rough sizes, Contact Simpson Strong-Tie.

Allowable loads have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
Download capacity is based on either the post design or concrete design calculated per code.
Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. For SCL columns, the fasteners for these products should always be installed in the wide face.
Testing to new ICC-ES acceptance criteria to be completed in 2009. Reference this web site for the latest loads and information.
NAILS: 16d = 0.162" dia. x 3 1/2" long. See other nail sizes and information.

PBS - Downloads may not be increased for short-term loading.
PBS - Designer to design concrete for shear capacity.
PBS - For higher downloads, solidly pack grout under 1" standoff plate before installing into concrete. Base download on column or concrete, according to the code.
Downloads shall be reduced where limited by buckling capacity of the post.
