The 12-gauge PB post base provides a connection between a post (or column) for decks, patio covers and other top-supported structures. Available with standard or ZMAX® galvanization, which offers extra corrosion resistance for outdoor or treated-wood applications.
Galvanized. Some products available in ZMAX or HDG coating. See Corrosion Information.
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).
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.
Loads may not be increased for short-term loading.
Concrete shall have a minimum compressive strength, f'c = 2500 psi.
Multiply Seismic and Wind ASD load values by 1.4 or 1.6 respectively to obtain LRFD capacities.
In accordance with IBC Section 1613.1, detached one- and two-family dwellings in Seismic Design Category (SDC) may use “Wind and SDC A&B” allowable loads.
Download shall be limited by the design capacity of the post. See Post Capacities for common post allowable loads.
For lateral loads for all PB models: F1 allowable = 765 lbs. F2 allowable = 1325 lbs.
Designer is responsible for concrete design.
Structural composite lumber columns have sides that either show the wide face or the edges of the lumber strands/veneers known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions due to narrow face installations.
