The Simpson 7" Beam Column Cap CCO7 1/8 by Simpson Strong-Tie is a legless beam cap engineered for reliable column-to-beam connections on top of steel columns and posts. Designed for field-welded attachment, this column cap features an extended seat that reaches beyond each side of the column to distribute beam loads effectively, making it a dependable choice for structural framing applications where column-to-beam integrity is critical.

Key Features

• Legless design for field-welded attachment - allows direct welding to steel columns, posts, pipe, or other column types, giving the designer full control over the connection in the field
• Extended seat beyond each side of the column - increases bearing surface area for improved load distribution from the beam, reducing stress concentration at the connection point
• Uplift load capacity increased for earthquake or wind loading - provides enhanced resistance under lateral and uplift forces, making it well suited for structures in high-wind or seismic zones
• Bolt spacing meets NDS code requirements - ensures the connection complies with recognized structural standards, supporting smooth inspections and project approvals
• Diamond holes included - allow temporary fastening during installation so the cap can be held securely in position before final welding is completed
• 3 gauge steel construction with no coating - delivers heavy-duty structural strength in a bare steel finish that is ready to accept field-applied treatments or welding as specified by the designer

Why This Product

• Built for demanding structural connections - the extended seat design actively distributes beam loads beyond the column footprint, reducing point loads and providing a more stable, balanced connection for wood beams on steel columns
• Flexible field installation - the legless, weld-ready format means the cap can be attached to a variety of steel column profiles including pipe columns, giving designers and contractors adaptability across different project conditions
• Code-compliant bolt hole requirements - bolt holes sized per 2018 NDS section 12.1.3.2 tolerances mean the connection is engineered to meet recognized building code standards, reducing the risk of compliance issues on the job site
• Engineered for elevated load demands - increased uplift load capacity addresses the real-world forces imposed by wind and seismic events, making this cap a practical choice for projects where performance under dynamic loading is a priority

Frequently Asked Questions

What type of columns is the CCO7 1/8 designed to attach to?

The CCO7 1/8 is designed for field-welded attachment to steel columns and posts. Its legless design accommodates this welded connection, and it may also be ordered for field welding to pipe or other column types, with welding performed by the designer.

What beam width does the CCO7 1/8 support?

The CCO7 1/8 is sized to support a 7-inch beam width. The seat of the column cap extends beyond each side of the column to provide additional bearing surface area and effective load distribution from the beam.

Does the CCO7 1/8 meet NDS code requirements?

Yes. The CCO7 1/8 features bolt spacing that meets NDS code requirements to ensure optimal 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 should be drilled from one side all the way through the beam to maintain proper hole tolerances.

Is the CCO7 1/8 suitable for high-wind or seismic applications?

Yes. The CCO7 1/8 features increased uplift load capacity designed to perform under earthquake or wind loading conditions, making it well suited for structural applications in areas subject to elevated lateral or uplift forces.
