CPS/PBV Standoff Bases

CPS/PBV

On This Page

The CPS is a composite plastic standoff base designed for use with hollow or solid wood columns, both indoors and outdoors. The line includes bases for 4x4, 4x6, 5x5, 6x6, 8x8,10x10 and 12x12 columns. All sizes are tested and load rated. The PBV is a hidden standoff post base. Two different shapes fit a variety of post sizes.

Material

  • CPS — engineered composite polymer; PBV — 14-gauge galvanized steel

Finish

  • PBV — black powder coat or galvanized

Installation

CPS/PBV
Post:

  • Drill a 3/4"-diameter hole, 10" into the center of the post.
  • Clean out dust. Fill hole halfway with Simpson Strong-Tie® SET-3G™ epoxy anchoring adhesive.
  • Insert all-thread rod and allow epoxy to set and cure.
  • Secure standoff to post using four 0.148" x 3" nails, except PBV which uses four Strong-Drive® SDS Heavy-Duty Connector screws.

Concrete:

  • Drill a 3/4"-diameter hole per anchor design (see table footnote 2).
  • Clean out dust. Fill hole halfway with Simpson Strong-Tie SET-3G epoxy anchoring adhesive. Insert post subassembly into hole and allow 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 PBV10P
  • For galvanized coating, order PBV6 or PBV10

Load Tables

CPS/PBV Standoff Bases Load Table
  1. Allowable uplift load capacities are for solid sawn posts with a specific gravity of 0.36 minimum — except the PBV, which is based on round "Viga" (ponderosa pine) wood posts.
  2. 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.
  3. 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).
  4. Allowable loads may not be increased for the duration of the load.
  5. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
