Product Description
The Simpson Strong-Tie CBT2Z-KT CBTZ 12-Gauge ZMAX Concealed Beam Tie by Simpson Strong-Tie is engineered to connect horizontal beams atop a vertical post while keeping the structural connection completely out of sight. Sized for a nominal 4x4 post, this concealed connector continues the structural load path into the foundation through the CPTZ, delivering both reliable performance and a clean, hardware-free appearance. Its cylindrical design allows installation with a common drill bit, eliminating the need for challenging kerf cuts, while ZMAX galvanization ensures lasting corrosion resistance in exterior and treated-wood applications.

Frequently Asked Questions
- What type of connection does the CBT2Z-KT make?
- The CBT2Z-KT is designed to connect horizontal beams atop a vertical post. It is part of a concealed connector system that continues the structural load path into the foundation through the CPTZ, providing a strong post-to-beam connection with no exposed hardware.
- Does this connector require special tools or cuts for installation?
- No special tools or kerf cuts are required. The simplistic cylindrical design allows installation with a common drill bit. Flattened sides let the installer use the CBTZ itself as a template, and locator tabs ensure proper dimensional layout.
- Why is the ZMAX finish important for this connector?
- ZMAX galvanization on the CBTZ offers extra corrosion resistance, making it suitable for exterior applications and use with treated wood where standard finishes may be insufficient. The included 1/2 in.-diameter drift dowels are also mechanically galvanized in accordance with ASTM B695, Class 55 for consistent corrosion protection throughout the assembly.
- Is this connector part of a larger concealed hardware system?
- Yes. The CBT2Z-KT is part of a concealed connector system that includes the CPTZ concealed post base and the CJT concealed joist tie, allowing for a completely concealed structural design throughout a project.
