The Simpson 5-1/8 in. Beam, 4x Post HDG Column Cap from Simpson Strong-Tie is a heavy-duty bolted connector engineered to create strong, reliable column-to-beam connections in wood construction. Finished in hot-dip galvanization, this column cap is built to perform in outdoor, exposed, and treated-lumber environments where moisture resistance is critical. Its extended seat design and certified weld construction make it a dependable choice for structural framing applications that demand consistent load transfer and code-compliant performance.

Key Features

• Hot-dip galvanized finish - provides a robust layer of corrosion resistance, keeping the connector performing reliably in outdoor, exposed, or treated-lumber applications where moisture and environmental exposure are ongoing concerns.
• Extended seat design - distributes beam load beyond each side of the column, increasing the bearing surface area and delivering superior structural support for demanding framing connections.
• Certified welds - give installers and engineers verifiable confidence in the strength and load capacity of every connection made with this cap.
• Uplift load capacity increased for seismic and wind loading - ensures the connector meets the elevated demands of earthquake- and wind-prone regions, adding a critical layer of safety to structural assemblies.
• Bolt spacing engineered to meet NDS code requirements - removes guesswork during installation and helps ensure inspections go smoothly on code-governed projects.
• Diamond holes for temporary fastening - allow the connector to be held securely in position before final bolting, simplifying alignment and speeding up the installation process.

Why This Product

• Purpose-built fit for 5-1/8 in. glulam and engineered beams - the cap is sized specifically for a 5-1/8 in. beam width, making it a precise match for common engineered lumber dimensions used in post-and-beam and timber-frame construction.
• Designed for 4x post connections - the column cap integrates directly with standard 4x post framing, reducing the need for custom fabrication and keeping structural connections straightforward and repeatable.
• Made in the United States by Simpson Strong-Tie - a trusted name in structural connectors, this cap is backed by the engineering standards and quality control that professionals rely on for load-critical framing work.
• Hot-dip galvanized durability for long-term outdoor performance - whether used in covered structures, pergolas, carports, or exposed timber framing, the HDG finish helps protect the connector from premature corrosion, reducing maintenance concerns over the life of the structure.

Frequently Asked Questions

What is the beam width this column cap is designed to accommodate?

The CC5 1/4-4HDG is designed for a beam width of 5-1/8 inches, with a W1 dimension of 5-1/4 inches to properly seat and secure the beam.

What bolt size is required for installation of the CC5 1/4-4HDG?

This column cap requires 3/4-inch bolts for installation. The bolt spacing is engineered to meet NDS code requirements for optimal structural performance.

Why is hot-dip galvanization important for this column cap?

The hot-dip galvanized finish provides a robust layer of corrosion resistance, making the CC5 1/4-4HDG well-suited for use in outdoor, exposed, or treated-lumber applications where moisture and environmental exposure are concerns.

How does the CC5 1/4-4HDG help manage load transfer in a column-beam connection?

The seat of the column cap provides additional surface area for bearing that extends beyond each side of the column. This design helps distribute the load from the beam and provides reliable support for the connection, which is particularly valuable in applications subject to earthquake or wind uplift forces.
