The Simpson CCOS Steel Column Cap delivers a high-capacity connection for column-to-beam combinations using 7 in. LVL, PSL, or LSL engineered wood products. Designed without column straps, this cap was created specifically for field welding to a steel column, allowing for a clean, direct attachment at the column end plate. For faster installation, the cap attaches to the column end plate using self-tapping screws (included), then connects to the girder with nails - keeping the fastening process straightforward on the job site.

Key Features

• Adequate bearing length for larger girder reactions - the 7-1/4 in. seat width distributes load effectively, making this cap well-suited for heavy structural applications where standard caps may fall short.
• Compatible with both solid sawn lumber and engineered wood products - gives contractors flexibility to use the cap across a range of beam types on the same project without sourcing multiple connectors.
• Self-tapping screws included - eliminates a trip to the fastener bin and keeps installation moving, since the cap attaches to the column end plate with a standard 5/16 in. hex driver.
• Made from 7-gauge steel - the heavy-gauge construction supports the high-load demands typical of column-to-girder connections in structural framing.
• G90 zinc galvanized finish - provides a durable corrosion-resistant coating that helps extend the service life of the connection in environments where moisture exposure is a concern.
• Strap-free design built for steel column applications - the absence of column straps is intentional, making this cap the right choice when the connector will be field welded directly to a steel column rather than attached mechanically.

Why This Product

• Purpose-built for steel column installations - the strap-free configuration was engineered specifically for field welding to a steel column, so buyers working with steel columns get a connector that fits the application rather than a modified workaround.
• Faster on-site assembly - self-tapping screws are included and the cap is designed to work with a common 5/16 in. hex driver, reducing the tools and separate fastener orders needed to complete the connection.
• Handles large structural loads - the 7-1/4 in. seat width provides adequate bearing length for larger girder reactions, making this cap a practical choice for heavy timber framing and engineered wood beam applications.
• Built-in corrosion protection - G90 galvanizing means the connector arrives ready for use in conditions where moisture could compromise an uncoated steel fitting, supporting long-term structural integrity without additional treatment.

Frequently Asked Questions

What type of column is the CCOS7.25 designed to attach to?

The CCOS7.25 was created specifically for field welding to a steel column. Its design omits the column straps found on standard column caps, making it ideal for steel column applications where direct welding is preferred.

What fasteners are used to install the CCOS7.25?

Attach the steel column cap to the column end plate using the (4) included self-tapping screws and a 5/16 in. hex driver. Attach the cap to the girder with 0.148 in. x 3 in. nails.

What beam or girder size is the CCOS7.25 compatible with?

The CCOS7.25 is sized for 7 in. LVL, PSL, or LSL engineered wood products, with a seat width of 7-1/4 in. to provide adequate bearing length for larger girder reactions.

What is the galvanizing specification, and why does it matter?

The CCOS7.25 is coated with G90 zinc galvanizing, which provides a durable layer of corrosion resistance. This finish helps protect the connector in environments where moisture exposure is a concern, extending the service life of the connection.
