The Simpson CPTZ Concealed Post Base works well with 4x4 or 6x6 deck posts that need to be covered by a composite sleeve.
The Simpson CPTZ Concealed Post Base incorporates a knife plate with a standoff base. It achieves a clean, concealed look while providing a 1" standoff height above concrete. The CPTZ is installed with 1/2" diameter galvanized pins (supplied). The 1" standoff height is code-required when supporting permanent structures that are exposed to weather or water splash, or in basements. The standoff reduces the potential for decay at post or column ends.
The anchorage for the CPTZ can be either cast-in-place or retrofit with adhesive or mechanical anchors. See Anchoring and Fastening Systems for Concrete and Masonry for additional information concerning retrofit solutions. This solution has been tested to determine capacity per the requirements of ICC-ES acceptance criteria AC399. Made of 10 gauge steel with ZMAX finish.
