The Simpson Strong-Tie CC3 1/4-4HDG Column Cap is a heavy-duty, hot-dip galvanized structural connector engineered to deliver reliable column-to-beam connections in wood construction. Designed for use with a 3-1/8" beam width and a 4x4 post, this column cap features an extended seat design that distributes load across a greater bearing surface area, providing superior support at critical structural junctions. Built to withstand demanding conditions, the hot-dip galvanized finish ensures lasting corrosion resistance in exposed or high-moisture environments.

Key Features

• Certified Welds: Engineered with certified welds for confidence in strength and structural loading performance
• Enhanced Uplift Loads: Uplift load values are increased to meet the demands of earthquake and wind loading applications
• NDS-Compliant Bolt Spacing: Bolt spacing meets NDS code requirements to ensure optimal structural performance
• Diamond Holes: Diamond-shaped holes allow for temporary fastening during installation
• Extended Bearing Seat: The seat extends beyond each side of the column to distribute beam loads effectively and support the connection
• Hot-Dip Galvanized Finish: Provides robust corrosion protection for use in exposed and treated-lumber environments
• Made in the United States: Manufactured domestically to Simpson Strong-Tie's high-quality standards

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.
