CPTZ Concealed Post Tie


The new CPTZ 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. The graphic and table below detail a possible cast-in-place solution. This solution has been tested to determine capacity per the requirements of ICC-ES acceptance criteria AC399.

Material: 10 gauge

Finish: ZMAX®; see Corrosion Information.
