The Simpson Triple 2X Beam Column Cap CCO4.62 from Simpson Strong-Tie is a legless column cap engineered for field-welded attachment to steel columns and posts, providing a strong and reliable connection at the top of a column where a triple 2X beam bears down. The extended seat reaches beyond each side of the column, creating additional bearing surface area that helps distribute beam loads effectively across the connection. Designed without legs, this cap gives structural designers the flexibility to weld it directly to steel columns, pipe columns, or other column types, with all welding performed by the designer on site.

Key Features

• Legless design for field-welded attachment - allows the cap to be welded directly to steel columns, pipe columns, or other column types on site, giving designers full control over the connection method without relying on pre-attached legs.
• Extended seat beyond each side of the column - increases the bearing surface area so beam loads are distributed more evenly across the connection, reducing stress concentration at the attachment point.
• Sized for triple 2X beam assemblies - the 4-1/2 in. beam width accommodation aligns precisely with a triple 2X built-up beam, making this cap a straightforward fit for common heavy timber and framing applications.
• Uplift load capacity increased for seismic and wind events - the connection is rated to handle elevated uplift forces from earthquake or wind loading, supporting structural performance where lateral and uplift demands are a design concern.
• Bolt spacing meets NDS code requirements - fastener layout is pre-engineered to satisfy code standards, reducing the design burden on the installer and helping projects stay compliant without additional engineering calculations for hole placement.
• 7 gauge steel construction with no coating - the heavy-gauge material provides the strength needed for demanding column-to-beam connections, and the uncoated finish makes it straightforward to field-weld without interference from surface treatments.

Why This Product

• Built for steel column integration - unlike caps with fixed legs sized for wood posts, this legless cap is purpose-designed to be welded to steel columns and pipe columns, making it the right tool when the structural system calls for a steel-to-wood interface at the column top.
• Engineered for code-compliant connections out of the box - bolt hole spacing and fastener requirements are pre-engineered to meet NDS standards, so designers and installers spend less time verifying compliance and more time completing the project.
• Handles real-world seismic and wind uplift demands - with uplift loads increased for earthquake and wind loading, this cap is suited for projects in high-demand climate or seismic zones where a standard connection would not meet the required performance threshold.
• Flexible field configuration for varied column types - the cap can be ordered for welding to pipe or other non-standard column profiles, giving design teams a single hardware solution adaptable to different structural column configurations on the same project.

Frequently Asked Questions

What type of columns is the CCO4.62 designed to attach to?

The CCO4.62 is designed for field-welded attachment to steel columns and posts. Its legless design makes it well suited for connecting directly to the top of steel columns, and it may also be ordered for field welding to pipe or other column types, with welding performed by the designer.

What is the beam width this column cap is rated for?

The CCO4.62 is designed to accommodate a beam width of 4-1/2 inches, making it appropriate for triple 2X beam assemblies commonly used in structural framing applications.

Does the CCO4.62 provide any resistance to uplift forces from wind or seismic events?

Yes. The CCO4.62 features increased uplift load capacity specifically to address forces associated with earthquake or wind loading, making it suitable for use in high-demand structural environments.

What do the diamond holes on the CCO4.62 serve?

The diamond holes on the CCO4.62 are provided for temporary fastening during the installation process, helping to hold the connector in position before final fastening and welding are completed.
