Build a solid foundation without having to look at an exposed post base when you’re finished. The Simpson Strong-Tie CPT66Z is a 6x6 concealed post tie that installs by cutting a slot in your post, which hides most of the connector out of sight and provides your deck, pergola or patio with the cleanest look you will find anywhere. Not only does the 1” standoff provide you with the height needed to keep your post from absorbing standing water, but it’s finished with a sleek black powder coat that will really make your project pop. If you’re looking to build your entire structure with concealed connectors, check out our CBTZ Concealed Beam Ties and CJTZ Concealed Joist Ties.

• The CPT66Z has been tested and load-rated for uplift, download and lateral load.
• The CPTZ anchorage can either be cast-in-place or retrofitted with adhesive or mechanical anchors.

• Use all specified fasteners. (all hardware in the photo is included)
• Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-braced, or non-top-supported installations.

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
