The Simpson CC78 Column Cap from Simpson Strong-Tie is a heavy-duty structural connector engineered to deliver strong, reliable column-to-beam connections in wood construction. Sized for a 6-3/4 in. wide beam and a nominal 8x post, this connector features a seat design that provides an additional surface area of bearing extending beyond each side of the column, helping to distribute the load from the beam and provide critical support at the connection point. Fabricated from 3-gauge steel with a Simpson Strong-Tie gray paint finish and certified welds throughout, this column cap is built to perform in demanding structural applications where both load transfer and uplift resistance are essential.

Key Features

• Certified welds - provide verified strength and load confidence, so you can trust the connection in critical structural applications
• Increased uplift load capacity - engineered to meet the heightened demands of earthquake and high-wind environments, giving structural connections the resistance they need where it matters most
• NDS code-compliant bolt spacing - ensures optimal performance and keeps installations aligned with code requirements, reducing the risk of inspection issues
• Diamond holes for temporary fastening - allow you to hold the cap in position during layout and alignment before final bolting, making installation more manageable
• 6-3/4 in. beam width and nominal 8x post size - precisely sized for heavy timber framing applications, ensuring a proper fit without field modification
• 3-gauge steel construction - delivers the structural mass and rigidity required for demanding column-to-beam load transfer applications
• Simpson Strong-Tie gray paint finish - provides a consistent, finished appearance and basic surface protection suited to the product's intended structural role
• Installs with six 3/4-in. diameter bolts - a defined hardware requirement that supports straightforward, code-aligned installation planning

Why This Product

• Built for high-load structural connections - the combination of 3-gauge steel, certified welds, and an extended bearing seat makes this column cap well suited for heavy timber framing where a standard-gauge connector would fall short
• Designed with seismic and wind uplift in mind - increased uplift load capacity means this connector is a dependable choice for wood construction projects in regions subject to earthquake or high-wind forces
• Simplifies code compliance - NDS code-compliant bolt spacing is built into the design, so the connection geometry works with code requirements from the start rather than requiring additional calculation or field adjustment
• Precise fit for a specific application - matched exactly to a 6-3/4 in. beam width and nominal 8x post, this cap eliminates guesswork and delivers a properly engineered fit for the timber sizes it was designed to connect
