Frequently Asked Questions
- How is the CB88 installed into concrete?
- The CB88 is designed to be either cast-in-place or wet set into concrete. In both methods, the bottom of the base plate sits flush with the concrete surface, ensuring full post bearing once the concrete has cured.
- What fasteners are required to install the CB88?
- Installation of the CB88 requires (2) 3/4-in. diameter machine bolts to secure the post to the column base.
- What steel gauge is used in the CB88 construction?
- The CB88 features a heavy-duty two-part steel construction: the strap is made from 3-gauge steel and the base plate is made from 7-gauge steel, providing the strength needed for high-load column applications.
- Is the CB88 suitable for use in high-wind or seismic zones?
- Yes. The CB88 is specifically designed with increased uplift resistance to perform under wind or seismic loading conditions, and its bolt hole locations meet code-required spacing for optimal load capacity.
