The Simpson CC74 6-3/4 in. Beam 4x Post Column Cap is a heavy-duty bolted connector from Simpson engineered to deliver secure, code-compliant column-to-beam connections in demanding wood-frame structural construction. Designed specifically for 6-3/4 in. wide beams paired with 4x post columns, this cap connector features an extended bearing seat that distributes load effectively across the connection point, providing the structural integrity required for post-and-beam assemblies subject to seismic and high-wind loading conditions.

Key Features

• Extended bearing seat design - reaches beyond each side of the column to distribute beam load across a greater surface area, reducing stress concentration at the connection and improving overall structural performance
• Engineered uplift load capacity - rated to resist forces generated by earthquake and high-wind loading, giving builders and engineers confidence in connections that must meet seismic and wind code requirements
• Certified weld construction - every weld is held to certified quality standards, so contractors can rely on consistent strength and predictable load performance on every installation
• 3/4 in. bolt fastening system - uses standard 3/4 in. bolts spaced to NDS code requirements, ensuring a straightforward installation process that meets recognized structural design standards
• Simpson gray paint finish - provides a protective coating suited to interior structural applications, helping the connector maintain its integrity over the life of the structure
• Domestic production - built in the United States to consistent manufacturing standards, supporting quality control from raw material to finished connector

Why This Product

• Purpose-built for 4x post applications - the CC74 is sized and engineered specifically for 4x post column installations with a 6-3/4 in. beam, eliminating the guesswork of adapting a general-purpose connector to a specific structural pairing
• Dual-hazard uplift resistance - with engineered capacity for both seismic and high-wind loading, this column cap addresses two of the most critical structural demands in a single connector, simplifying the specification process for engineers and contractors
• Code-compliant bolt spacing - the bolt pattern is engineered to NDS requirements, so the connection is designed to satisfy code review without requiring custom engineering workarounds
• Configurable for non-standard lumber - straps can be rotated 90 deg. and an optional W2 dimension can be specified for rough-cut or custom lumber sizes, making this connector adaptable to real-world framing conditions beyond standard dimensional lumber

Frequently Asked Questions

What beam width is the CC74 designed to fit?

The CC74 is designed for use with a 6-3/4 in. wide beam, making it suitable for structural column-to-beam connections where that beam dimension is specified.

What bolt size is required for installing the CC74?

The CC74 requires 3/4 in. bolts. The bolt spacing is engineered to meet NDS code requirements for optimal structural performance.

What is the purpose of the extended seat design on the CC74?

The extended seat design provides additional bearing surface area that reaches beyond each side of the column, distributing the load from the beam more effectively and reinforcing the integrity of the overall structural connection.

Is the CC74 suitable for use in areas with seismic or high-wind conditions?

Yes. The CC74 features increased uplift load capacity that is specifically engineered to meet the demands of earthquake and wind loading conditions, along with certified welds for confidence in strength and loading performance.
