Simpson Strong-Tie CPS Composite-Plastic Standoff Post Base

Simpson Strong-Tie

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).
