CBTZ Concealed Beam Tie
CBTZ, the newest addition to the concealed structural connector line, combines structural strength with invisibility. Designed to connect horizontal beams atop a vertical post, the CBTZ continues the structural load path into the foundation through the CPTZ. The simplistic cylindrical design allows installations with a common drill bit, eliminating challenging kerf cuts. The CBTZ is available in two models designed to connect beams and posts of a variety of sizes. It is part of a concealed connector system that includes the CPTZ and CJT.
- Flattened sides assist installer while using the CBTZ as a template
- Locator tabs provide proper dimensional layout
- Required dowel pins included
- Orientation markings distinguish which end installs into the post and which end goes into the beam
- CBT — ZMAX® coating; the 1/2"-diameter drift dowels are mechanically galvanized in accordance with ASTM B695, Class 55
- Use all specified fasteners; see General Notes
- 1/2" dowels included
- CBT2Z requires a minimum 6"-deep nominal beam
