The Simpson ECC64 End Column Cap by Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction framing. Sized for a nominal 6x beam and 4x post, this end column cap features a seat that extends beyond one side of the column to provide additional bearing surface area, helping to distribute load from the beam and maintain a secure, supported connection where it matters most.

Key Features

• Certified welds - provide verified strength and loading confidence, so you know the connection meets a defined structural standard before installation begins
• Increased uplift load ratings - designed to handle the demands of earthquake and high-wind loading, giving this cap a meaningful advantage in seismic zones and storm-prone regions
• Bolt spacing that meets NDS code requirements - takes the guesswork out of compliance, ensuring the fastener layout achieves optimal structural performance right out of the box
• Diamond holes for temporary fastening - allow you to hold the cap in position during layout and alignment before committing to final installation, reducing the chance of costly errors
• 7-gauge steel construction - delivers the thickness and rigidity needed for heavy structural connections between 6x beams and 4x posts
• Simpson Strong-Tie gray paint finish - provides a consistent, finished appearance suited for exposed timber framing applications

Why This Product

• Built for end-of-beam structural connections - the extended seat design distributes beam load across additional bearing surface area, making this cap specifically suited for end-column applications where a standard cap would leave load transfer incomplete
• Rated for seismic and wind uplift demands - uplift loads are increased to address earthquake and wind loading scenarios, making this a practical choice for projects in high-load design environments
• Code-compliant fastener layout included - bolt spacing is engineered to meet NDS requirements, which simplifies the inspection and approval process on permitted structural projects
• Domestic manufacturing with certified weld quality - Simpson Strong-Tie produces this column cap in the United States with certified welds, supporting consistent quality control for a connection that carries real structural responsibility

Frequently Asked Questions

What is the ECC64 designed to do?

The ECC64 End Column Cap is designed to provide strong column-beam connections in end-of-beam applications in wood construction. The seat extends beyond one side of the column to provide additional bearing surface area, helping to distribute the load from the beam and support the connection.

What size beam and post does the ECC64 fit?

The ECC64 is sized for a nominal 6x beam width and a nominal 4x post size, making it suitable for common structural lumber dimensions used in wood construction framing.

What fasteners are required to install the ECC64?

Installation requires four (4) 5/8 in. diameter machine bolts - two for the beam and two for the post - to secure the column cap and achieve the rated load values.

Is the ECC64 rated for seismic and high-wind conditions?

Yes. The ECC64 features uplift loads increased for earthquake or wind loading, certified welds, and bolt spacing that meets NDS code requirements, making it suitable for use in seismic and high-wind design applications.
