Product Overview

The CPTZ post base incorporates a knife plate with a standoff base. It achieves a clean, concealed look while providing a 1 in. standoff height above concrete. The CPTZ is installed with 1/2 in. diameter galvanized pins (supplied).
  • The 1 in. 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
  • Nominal post size: 6x6
  • Base: 12 ga.; knife plate: 10 ga.
  • ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
  • Install with 1/2 in. anchor bolts and supplied dowels

Answer

The CPT66Z anchors to the concrete with 2 - 1/2" diameter anchors. It is up to the Designer to specify the anchor bolt type (i.e. cast-in-place, mechanical, adhesive), length and embedment. Thank you!

I really like the idea of these post base because I did not want any hardware showing on the base of my newly installed 6 x 6 post leading to my front door. However; my contractor hated them & we gave up on trying to use these. it was diffident to get the 3 metal plugs to align perfectly.

Is this base appropriate for attaching a wooden handrail to a concrete porch and steps?

Asked by Zuni March 6, 2019

Answer

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, railings or unbraced carports). We do not have a base to recommend for railing applications to existing concrete. Thank you!

Answer

It would be up to the Designer/Engineer of Record to specify the orientation depending on the lateral load demands. (The F2 direction is rated higher than the F1 direction; please see our website or current catalog for details). Thank you!

an you tell me the center to center measurement for the base that you anchor to bracket to

Asked by Checken June 21, 2017

Answer

The holes are 2 1/4" apart center-to-center, but they are staggered - on opposite sides and opposite ends of the knife plate. Its not easy to give a clear picture in words...I would suggest visiting our website and looking at the "Installation" images in the gallery on the CBT page for a clear picture. Thank you!

What is the measurement center to center of the anchor bolt holes? Are they directly across from each other or stagged

Asked by Chicken June 20, 2017
1
Answer

The top two holes are 2 1/4" apart center-to-center and the third hole is at the centerline between those two, but 1.5" lower (center-to-center). This base has a knife plate that is inserted into a 3/16"-wide slot cut in the end of the post and then 1/2"-diameter drift dowels are inserted in pre-drilled post holes and through the knife plate. Please visit our website for complete installation information. Thank you!
