The Simpson Strong-Tie Cross Column Cap is an engineered, multiple-beam, bolted column cap designed to create strong, reliable connections where multiple wood beams intersect at the top of a single column. By distributing loads from intersecting beams across a single connection point, this cross column cap delivers dependable structural support for complex framing configurations. Each unit is manufactured to specific designer details, accommodating a wide range of beam and post size combinations to meet the precise requirements of any structural project.

Key Features

• Multiple-beam, cross column cap configuration - allows several wood beams to bear on top of a single column, simplifying complex framing intersections and reducing the need for multiple separate connectors.
• 7 gauge or 3 gauge steel construction depending on size - heavier gauge options are available for larger, higher-load applications, giving structural designers the right strength level for each specific project.
• Simpson Strong-Tie Gray paint finish with HDG available - the standard painted finish provides corrosion resistance for typical interior framing, while hot-dip galvanized is available for projects requiring additional protection in harsher environments.
• Engineered load distribution with defined side beam limits - the side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb, and the sum of loads for the side beam(s) and main beam cannot exceed the table load, giving designers clear, reliable parameters for safe load planning.
• Compatible with steel column applications when ordered without column straps - specifying CCOC, CCOT, or ECCOL allows field welding by the designer with full loads applying, broadening the range of structural systems this cap can serve.
• Custom-fabricated per designer details - because each unit is specified to exact project requirements, the cap fits the precise beam and post size combination needed rather than forcing a compromise with a standard off-the-shelf size.
• Column width in the direction of the main beam matches the main beam width (W1) - this design requirement ensures a flush, properly aligned connection that supports accurate load transfer and clean framing geometry.

Why This Product

• Built for multi-beam intersections that standard caps cannot handle - where multiple wood beams converge at the top of a single post, this cross column cap consolidates all connections into one engineered solution, reducing complexity and improving structural integrity at critical load points.
• Engineered to verified load limits with no guesswork - clearly defined allowable loads, a 40% side beam maximum, and a combined load cap give structural designers and engineers exact figures to work with, supporting accurate, code-conscious framing design.
• Flexible enough for both wood and steel column systems - the option to order without column straps for field welding to steel columns means this bolted column cap adapts to a broader range of structural framing systems beyond standard wood post construction.
• Precision-specified to match your exact project - because each cap is manufactured to specific designer details across many combinations of beam and post sizes, the connection performs as engineered rather than approximated, supporting confidence in long-term structural performance.

Approved Applications

• Column-to-beam connections where multiple wood beams bear on top of a single column
• Structural framing systems requiring load distribution from intersecting beams

Load Considerations

• The download shall be determined from the allowable loads for the unmodified product
• The side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb
• The sum of the loads for the side beam(s) and main beam cannot exceed the table load
• Uplift loads do not apply for ECCL caps; for CCC and CCT, uplift loads from the table apply for the main beam only

Options

• Many combinations of beam and post sizes can be manufactured. Refer to worksheet Options for Multiple-Beam, Bolted Column Caps.
• The download shall be determined from the allowable loads for the unmodified product (see the Specifications link). The side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb. The sum of the loads for the side beam(s) and main beam can not exceed the table load.
• Uplift loads do not apply for ECCL caps. For CCC and CCT, uplift loads from table apply for main beam only.
• The column width in the direction of the main beam width must be the same as the main beam width (W1).
• Specify the stirrup height from the top of the cap. The minimum side stirrup heights (H2 or H3) is 6 1/2" (3 1/2" for 44s).
• The L dimension may vary depending on the width of the side stirrup (W3 or W4).
• Column caps may be ordered without the column straps for field welding to a steel column. Specify CCOC/CCOT/ECCOL. Weld by Designer. Full loads apply.

Frequently Asked Questions

What steel gauges are used for the Simpson CCC Cross Column Cap?

The CCC is manufactured from either 7 gauge or 3 gauge steel, with the specific gauge depending on the size of the cap required for your application.

Can the CCC be ordered for use with a steel column instead of a wood column?

Yes. Column caps may be ordered without column straps, which allows for field welding directly to a steel column rather than bolting to a wood post.

Is the Simpson CCC a standard stock item, or is it custom-made?

The CCC is manufactured to specific designer details and accommodates many combinations of beam and post sizes. Because it is custom-made to meet the precise requirements of each project, it is non-returnable.

What finish options are available for the CCC, and does the uplift load rating apply to all beams in the connection?

The CCC comes standard with a Simpson Strong-Tie Gray paint finish for corrosion resistance, and a Hot-Dip Galvanized (HDG) finish is also available by contacting for a quote. Regarding load ratings, the uplift loads listed in the table apply to the main beam only and do not cover all intersecting beams in the connection.
