The Simpson CC3 1/4-4HDG Column Cap is a hot-dip galvanized structural connector built for dependable column-to-beam connections in wood-frame construction. Sized for a 3-1/8 in. beam width and a 4x post, this connector is engineered to handle the structural demands of post-and-beam framing while standing up to outdoor and high-moisture environments. Whether you are reinforcing against lateral forces or securing a load-bearing junction in an exposed setting, this Simpson column cap delivers the strength and corrosion resistance that critical structural connections require.

Key Features

• Hot-Dip Galvanized Finish - Provides robust corrosion resistance for use in outdoor, exposed, or high-moisture environments, including applications involving treated lumber.
• Certified Welds - Engineered with certified welds so you can have confidence in the connector's strength and structural loading performance at every joint.
• Enhanced Uplift Load Values - Increased uplift capacity meets the demands of earthquake and wind loading applications, adding security in high-stress structural scenarios.
• Extended Seat Design - Distributes load across a greater bearing surface area, providing superior support at critical post-to-beam junctions.
• Rotatable Strap Option - Straps may be rotated 90 deg., giving installers flexibility to adapt the connector to varying framing orientations without additional hardware.
• Domestic Manufacturing - Produced in the United States, supporting consistent quality standards in materials and fabrication.

Why This Product

• Purpose-Built Sizing for a Common Framing Pairing - Designed specifically for a 3-1/8 in. beam width paired with a 4x post, this column cap fits engineered lumber and dimensional lumber combinations used frequently in residential and light commercial post-and-beam construction.
• Ready for Demanding Load Conditions - Enhanced uplift load values mean this connector is suited for structures in seismic zones or high-wind regions, helping builders meet code requirements without sourcing specialty hardware.
• Long-Term Performance in Tough Environments - The hot-dip galvanized finish is specifically appropriate for exposed structural applications and treated lumber contact, reducing the risk of corrosion-related failure over the life of the structure.
• Installation Flexibility Built In - The ability to rotate straps 90 deg. means the connector adapts to different framing orientations on the job site, reducing the need for workarounds and keeping projects moving efficiently.

Frequently Asked Questions

What beam width and post size is the CC3 1/4-4HDG designed for?

This column cap is designed for use with a 3-1/8" beam width and a 4x4 post, making it suitable for standard engineered lumber and dimensional lumber applications at those specific sizes.

Is this column cap suitable for outdoor or high-moisture environments?

Yes. The CC3 1/4-4HDG features a hot-dip galvanized finish that provides robust corrosion resistance, making it appropriate for exposed environments and applications involving treated lumber where moisture contact is a concern.

Does this connector meet code requirements for earthquake and wind loading?

Yes. The CC3 1/4-4HDG is engineered with enhanced uplift load values to meet the demands of earthquake and wind loading applications. Additionally, bolt spacing is designed to meet NDS code requirements for optimal structural performance.

What installation features does the CC3 1/4-4HDG include to simplify the process?

The column cap includes diamond-shaped holes that allow for temporary fastening during installation, and features an extended bearing seat that extends beyond each side of the column to distribute beam loads effectively across a greater bearing surface area.
