The Simpson CC5 1/4-8 Column Cap from Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections in wood construction. The seat of the column cap provides an additional surface area of bearing that extends beyond each side of the column, helping to distribute the load from the beam and provide critical support for the connection. Built from heavy-duty 3-gauge steel with a durable gray paint finish and certified welds, this column cap is sized for a 5-1/8 in. beam width paired with a nominal 8x post. Whether your structural framing project demands resistance to standard loads or enhanced performance under seismic or high-wind conditions, this column cap is designed to meet the challenge.

Key Features

• Certified welds - provide verified strength and load confidence, so you can trust the connection at every joint without second-guessing the assembly.
• Increased uplift load ratings - engineered for earthquake and high-wind loading scenarios, giving your structure added resilience where environmental forces are a concern.
• NDS code-compliant bolt spacing - eliminates guesswork during installation and helps ensure your connection meets code requirements the first time.
• Diamond holes for temporary fastening - allow you to hold the cap in position during layout and alignment before final bolting, simplifying the installation process.
• 3-gauge steel construction - delivers heavy-duty strength suited for demanding structural framing applications where load transfer and durability are critical.
• Simpson Strong-Tie gray paint finish - provides a protective coating that resists corrosion in typical covered wood construction environments, helping the connector maintain its integrity over time.

Why This Product

• Purpose-built sizing for a secure fit - designed specifically for a 5-1/8 in. beam and nominal 8x post, this column cap eliminates the fitment concerns that come with general-purpose hardware, supporting a tight and structurally sound connection.
• Dual-purpose uplift performance - with uplift loads increased for both earthquake and wind loading, this connector addresses two of the most demanding conditions in structural wood framing, making it a practical choice for projects in high-load regions.
• Heavy-gauge steel for load-critical connections - at 3-gauge steel, the column cap is built to handle the load distribution demands of post-and-beam framing, providing the bearing area and material strength the connection requires.
• Backed by trusted engineering - certified welds and NDS code-compliant bolt spacing reflect the engineering rigor that Simpson Strong-Tie applies to its structural connectors, supporting builder confidence during both installation and inspection.
