CPS Composite-Plastic Standoff Post Base
Product Details
The CPS is a composite-plastic standoff base designed for use both indoors and outdoors. The CPS attaches to the bottom of the solid wood column and to concrete with threaded rod and epoxy. The CPS is load rated and features either a square or a rectangle shape depending upon post dimensions.
Key Features
- Provides code-required 1" standoff
- Multiple sizes to support a variety of projects
- Black finish for a custom look
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 0.148" x 3" nails.
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, 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).

Load Tables
These products are made from non-corrosive materials.
- Allowable uplift load capacities are for solid sawn posts with a specific gravity of 0.36 minimum.
- 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.
- Allowable loads may not be increased for the duration of the load.
- 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.
