The Simpson 6-3/4" Beam Column Cap CCO7 from Simpson is a heavy-duty column cap engineered to create strong, reliable connections between beams and steel columns. Built for structural applications where a secure column-to-beam connection is critical, this cap features a legless design intended for field-welded attachment to steel columns and posts, along with an extended seat that distributes beam loads across a wider bearing surface for added stability and performance.

Key Features

• Legless design for field-welded attachment - allows the cap to be welded directly to steel columns and posts on-site, giving installers the flexibility to fit the connection to the structure rather than the other way around
• Extended seat with additional bearing surface area beyond each side of the column - spreads beam loads more evenly at the connection point, reducing stress concentration and improving overall structural integrity
• Uplift load capacity increased for earthquake or wind loading - provides enhanced resistance in high-load events, making this cap suitable for applications in demanding environmental conditions
• Bolt spacing meets NDS code requirements - ensures the connection performs to recognized engineering standards without requiring additional field calculations or modifications
• Diamond holes included - allow for temporary fastening during installation, keeping the cap securely positioned while permanent welding or fastening is completed
• 3 gauge steel construction with no coating - delivers substantial material strength in a form ready for field welding or custom finishing as required by the project

Why This Product

• Purpose-built for steel column connections - the legless, weld-ready design addresses a specific structural need that standard post caps cannot fulfill, making it a practical choice for steel-framed construction and mixed-material projects
• Engineered for code-compliant performance - bolt spacing that meets NDS requirements and increased uplift load capacity mean the CCO7 supports both everyday structural loads and exceptional forces from wind or seismic events
• Flexible installation on multiple column types - compatible with steel columns, posts, pipe columns, and other column configurations, giving designers and builders adaptability across a range of project types without sourcing multiple products
• American-made quality in a robust 3 gauge steel body - the combination of domestic manufacturing and heavy-gauge steel construction reflects a commitment to durability and consistency in critical load-path connections

Frequently Asked Questions

What type of columns is the CCO7 designed to attach to?

The CCO7 is designed for use on top of steel columns and posts. Its legless design is specifically intended for field-welded attachment to steel columns, and it may also be ordered for field welding to pipe or other column types, with welding performed by the designer.

How does the CCO7 help distribute loads from the beam?

The seat of the CCO7 column cap provides additional bearing surface area that extends beyond each side of the column. This extended seat design helps to distribute the load transferred from the beam and provides enhanced support at the connection point.

Does the CCO7 meet code requirements for bolt spacing?

Yes. The CCO7 features bolt spacing that meets NDS code requirements to ensure optimal structural performance. Per the 2018 NDS (section 12.1.3.2), bolt holes should be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter and drilled from one side all the way through the beam to maintain proper hole tolerances.

Is the CCO7 suitable for use in high-wind or seismic zones?

Yes. The CCO7 is designed with increased uplift load capacity to address the demands of earthquake and wind loading conditions, making it appropriate for use in seismic and high-wind applications where enhanced connection performance is required.
