PBV Post Base (for Viga Post)
Product Details
The PBV is designed to make a hidden connection between viga posts and concrete. This circular, hidden standoff post base attaches to concrete with threaded rod and epoxy to the bottom of the viga post with Strong-Drive® SDS Heavy-Duty Connector screws for a secure connection. The PBV comes in two different sizes to support a variety of projects.
Key Features
- Round shape to match viga-style posts
- Black powder-coated finish
- 1" standoff to help prevent rot at the end of the post
Material
- 14 gauge
Finish
- Black powder coat or galvanized
Installation
Post:
- Drill a 3/4"-diameter hole, 10" into the center of the post.
- Clean out sawdust. Fill hole halfway with Simpson Strong-Tie® SET-3G™ epoxy anchoring adhesive.
- Insert all-thread rod while twisting the rod, and allow the epoxy to set and cure.
- Secure standoff to post using four Strong-Drive SDS Heavy-Duty Connector screws (sold separately).
Concrete:
- Drill a 3/4"-diameter hole per anchor design a min. 4 3/4" from the edge
- Clean out dust. Fill hole halfway with Simpson Strong-Tie SET-3G, ET-3G™ or AT-3G™ anchoring adhesive. Insert post subassembly into hole, and allow the epoxy to set and cure.
- 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)
Ordering Information
- For black powder coat, order PBV6PC or PBV10PC. For galvanized coating, order PBV6 or PBV10.

Load Tables
- Allowable uplift load capacities are based on round “Viga” (ponderosa pine) wood posts.
- All allowable uplift loads are based on a lowest ultimate load from testing divided by a safety factor of 4. Concrete anchorage to be designed by others; refer to the Simpson Strong-Tie® Anchoring, Fastening and Restoration Systems for Concrete and Masonry catalog. Uplift loads shall not exceed those shown in the table.
- Downloads are calculated based on the standoff bearing area and a concrete strength of 2,500 psi — except the PBV, which is based on the wood’s bearing strength (700 psi for ponderosa pine).
- Allowable loads may not be increased for the duration of the load.
- SDS screws are Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
