Product Description
The Simpson CC88 Column Cap is a heavy-duty steel connector engineered by Simpson Strong-Tie to create strong, reliable column-to-beam connections in wood frame construction. Sized specifically for nominal 8x beams and 8x posts, this connector features a precision-formed seat that extends beyond each side of the column, increasing the bearing surface area to effectively distribute load from the beam down through the post. Fabricated from 3-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, the CC88 is built to handle both standard structural loads and the elevated uplift demands imposed by earthquake and wind loading - making it a dependable choice for decks, pergolas, covered porches, and structural framing systems where code-compliant performance is non-negotiable.
Key Features
- Certified welds - provide verified strength and loading confidence so you can trust the connection in demanding structural applications
- Increased uplift load capacity - engineered to handle elevated forces from earthquake or wind loading, adding a critical layer of protection in high-stress environments
- NDS code-compliant bolt spacing - meets National Design Specification requirements, helping your project pass inspection without costly rework
- Diamond holes for temporary fastening - allow you to hold the cap in position during installation before final bolting, simplifying the process on the job site
- Extended seat bearing surface - projects beyond each side of the column to distribute beam load more evenly, reducing point stress at the connection
- 3-gauge steel construction - delivers heavy-duty strength suitable for load-bearing structural framing where connector integrity is critical
- Simpson Strong-Tie gray paint finish - provides a clean, consistent appearance while offering a baseline level of corrosion resistance for the connector
- Installed with six 3/4-in. diameter bolts - a defined fastener requirement that takes the guesswork out of hardware selection and supports a secure, repeatable installation
Why This Product
- Built specifically for 8x-to-8x connections - rather than a general-purpose connector adapted to fit, the CC88 is designed from the ground up for nominal 8x beam and 8x post pairings, delivering a precise fit and optimized load transfer for this common structural pairing
- Engineered for seismic and wind uplift demands - with uplift loads specifically increased for earthquake and wind loading, this column cap addresses the real-world forces that standard connectors may not adequately handle, giving builders and homeowners added peace of mind in challenging conditions
- Confidence through certified welds and code compliance - certified welds combined with NDS code-compliant bolt spacing mean the CC88 is not just strong, it is verifiably strong, supporting smoother inspections and greater trust in the finished structure
- Simplified installation with built-in positioning features - diamond holes allow temporary fastening to hold the cap in place while bolts are set, reducing alignment errors and making the installation process more efficient on complex framing projects

Frequently Asked Questions
- What post and beam sizes is the CC88 compatible with?
- The CC88 is designed specifically for use with 8x nominal beams and 8x nominal posts. It is not intended for use with smaller or larger member sizes outside of this 8x pairing.
- How is the CC88 installed, and how many bolts are required?
- The CC88 is installed using six 3/4-inch diameter bolts. The bolt spacing is designed to meet NDS code requirements for optimal performance. The connector also includes diamond holes to allow for temporary fastening during installation.
- What material and finish is the CC88 made from?
- The CC88 is fabricated from heavy-duty 3-gauge steel with certified welds and is finished with a Simpson Strong-Tie gray paint coating.
- Is the CC88 suitable for high-wind or seismic applications?
- Yes. The CC88 features uplift loads increased for earthquake or wind loading, making it appropriate for structural applications where elevated uplift demands from high-wind or seismic conditions must be addressed.
