Frequently Asked Questions
- How is the CB88HDG installed into concrete?
- The CB88HDG can be installed either cast-in-place or wet set into the concrete. In both methods, the bottom of the base plate sits flush with the concrete surface to ensure full post bearing beneath the column.
- What fasteners are required to install the CB88HDG?
- Installation requires (2) 3/4-in. diameter hot-dip galvanized (HDG) machine bolts to secure the column base.
- Why is hot-dip galvanization important for this column base?
- Hot-dip galvanization (HDG) provides an extra layer of corrosion resistance, making the CB88HDG especially well suited for exterior environments and applications involving treated lumber, where moisture and chemical exposure are concerns.
- What wood member sizes are compatible with the CB88HDG?
- The CB88HDG is sized for a nominal 8x8 column and is compatible with a wide range of lumber, glulam, and engineered wood products of that nominal dimension.
