Product Description
Simpson CCO4 CCO Column Cap (No Legs) for 4x Beam, 4 in. Height by Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections on top of steel columns and posts. The legless design enables field-welded attachment directly to steel columns, while the extended seat provides additional bearing surface area beyond each side of the column to effectively distribute beam loads and support the connection.

Frequently Asked Questions
- What beam width is the CCO4 designed to support?
- The CCO4 is designed for nominal 4x or 3-1/2 in. beam widths, making it compatible with standard dimensional lumber in that size range.
- Why does the CCO4 column cap have no legs?
- The legless design of the CCO4 allows for field-welded attachment directly to steel columns and posts, offering greater flexibility in steel column applications where a welded connection is preferred or required.
- How does the CCO4 perform under earthquake or high-wind conditions?
- The CCO4 features increased uplift load capacity specifically to address the demands of earthquake and wind loading, helping to maintain structural integrity under these dynamic forces.
- What fasteners are required to install the CCO4?
- Installation of the CCO4 requires (2) 5/8 in. diameter machine bolts. Diamond holes are also provided on the cap to allow for temporary fastening during the installation process, and bolt spacing meets NDS code requirements for optimal performance.
