The Simpson CC3 1/4-4 Column Cap is engineered by Simpson to deliver strong, reliable column-to-beam connections in wood construction. Sized specifically for a 3-1/8 in. wide beam and a nominal 4x post, the seat of this column cap provides an additional surface area of bearing that extends beyond each side of the column, helping to distribute the load from the beam and provide solid support for the connection. Fabricated from heavy-duty 7-gauge steel with certified welds and a durable Simpson Strong-Tie gray paint finish, this post-and-beam connector is built to perform under demanding structural loads in both residential and commercial framing applications.

Key Features

• Certified Welds - Provide confidence in strength and loading performance, so builders can trust the connection under real structural demand.
• Increased Uplift Load Capacity - Uplift loads are increased for earthquake or wind loading, making this column cap a strong choice for structures in high-wind or seismic zones.
• NDS-Compliant Bolt Spacing - Bolt spacing meets NDS code requirements, helping ensure optimal performance and smoother inspections on the job site.
• Diamond Holes for Temporary Fastening - Allow the cap to be held in place during positioning, making installation easier and more accurate before final bolting.
• 7-Gauge Steel Construction - Heavy-gauge steel delivers the structural rigidity needed for demanding post-and-beam assemblies.
• Simpson Strong-Tie Gray Paint Finish - Provides a protective coating suited for interior structural applications while maintaining a clean, consistent appearance.
• Installs with (6) 5/8-in. Diameter Bolts - Straightforward fastener requirements keep the installation process clear and predictable (fasteners sold separately).

Why This Product

• Built for Demanding Load Conditions - With certified welds and uplift loads increased for earthquake or wind loading, this column cap is engineered to hold up where structural performance matters most, including high-wind and seismic construction zones.
• Code-Ready Design - Bolt spacing that meets NDS code requirements takes the guesswork out of compliance, helping contractors and builders move through inspections with greater confidence.
• Precise Fit for a Specific Beam-and-Post Combination - Designed exclusively for a 3-1/8 in. beam and nominal 4x post, the CC3 1/4-4 provides a properly sized, load-distributing seat connection rather than a generic catch-all bracket, resulting in a more reliable structural assembly.
• Practical Installation Features - Diamond holes allow for temporary fastening during positioning, and a clearly defined six-bolt installation pattern keeps the process straightforward for framing crews working on post-and-beam or column-to-beam connections.

Frequently Asked Questions

What beam width and post size is the CC3 1/4-4 designed to fit?

The CC3 1/4-4 is designed for use with a 3-1/8 in. wide beam and a nominal 4x post, making it specifically sized for that beam-to-post combination in wood construction.

How is the CC3 1/4-4 installed, and what fasteners are required?

The CC3 1/4-4 is installed using six 5/8 in. diameter bolts. It also features diamond holes to allow for convenient temporary fastening during the installation process before final bolting.

What material and finish is used on the CC3 1/4-4?

The CC3 1/4-4 is made from 7-gauge steel and features certified welds for confident strength and loading performance. It is finished with a Simpson Strong-Tie gray paint coating for lasting durability.

Is the CC3 1/4-4 suitable for use in areas subject to earthquake or high-wind conditions?

Yes. The CC3 1/4-4 features increased uplift load capacity specifically to address earthquake and wind loading requirements. Its bolt spacing also meets National Design Specification (NDS) code requirements to ensure optimal structural performance in demanding conditions.
