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.
- 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.
- NAILS: 16d = 0.162″ dia. x 3 1/2″ long. See other nail sizes and information.
- For higher downloads, solid pack grout under 1″ standoff plate before installing PBS into concrete. Base download on column or concrete, according to the code.
- 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) C may use “Wind and SDC A&B” allowable loads.
- 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).
- Download shall be reduced where limited by the design capacity of the post. See Post Capacities for common post allowable loads.
- Designer is responsible for concrete design.
- For lateral loads for all PBS models: F1 allowable = 1165 lbs. when using nails and 230 lbs. when using bolts. F2 allowable = 835 lbs. when using either nails or bolts.
