The Simpson Strong-Tie CC88HDG Column Cap is a heavy-duty, hot-dip galvanized connector engineered to deliver reliable column-to-beam connections in demanding wood construction applications. Designed specifically for 8x8 post and 8x beam configurations, this column cap features a robust seat that extends beyond each side of the column, providing an expanded bearing surface that effectively distributes load from the beam while delivering solid support at the connection point. With certified welds, increased uplift load capacity, and code-compliant bolt spacing, the CC88HDG is built to perform where structural integrity matters most.

Key Features

• Certified welds for confidence in strength and loading
• Uplift loads increased for earthquake or wind loading applications
• Bolt spacing meets NDS code requirements to ensure optimal structural performance
• Diamond holes provide temporary fastening during installation
• Hot-dip galvanized finish for enhanced corrosion resistance in exposed or treated-lumber environments
• Seat design provides additional surface area of bearing that extends beyond each side of the column
• Helps distribute load from the beam and provides support for the connection

Frequently Asked Questions

What post and beam sizes is the CC88HDG compatible with?

The CC88HDG is designed specifically for 8x8 post and 8x beam configurations. Both the W1 and W2 dimensions are 7-1/2 in., confirming compatibility with standard 8x lumber dimensions.

Why is the hot-dip galvanized finish important for this column cap?

The hot-dip galvanized finish provides enhanced corrosion resistance, making the CC88HDG well-suited for use in exposed outdoor environments or applications where pressure-treated lumber is used, which can accelerate corrosion in connectors with lesser finishes.

Is the CC88HDG suitable for use in high-wind or seismic zones?

Yes. The CC88HDG features increased uplift load capacity, which is specifically intended to address the demands of earthquake or wind loading applications, making it appropriate for use in high-wind or seismic environments.

What bolt size does the CC88HDG require, and does it meet code requirements?

The CC88HDG uses 3/4 in. bolts, and its bolt spacing is designed to meet NDS code requirements to ensure optimal structural performance at the connection point.
