The Simpson ECC74 End Column Cap is a heavy-duty structural connector from Simpson built specifically for end-of-beam column-to-beam connections in wood construction. Engineered to fit a 6-3/4 in. beam with a 4X post, this end column cap provides dependable load distribution from beam to post while delivering increased uplift resistance for structures in earthquake- or wind-prone environments. Its robust 3-gauge steel construction and certified welds make it a trusted solution for contractors and builders who need code-compliant, high-strength connections at beam ends.

Key Features

• 3-gauge steel construction - delivers the structural rigidity and load-bearing capacity needed for demanding beam-to-post connections in wood framing applications
• Certified welds - gives builders confidence that every joint meets strength and loading requirements without on-site guesswork
• Increased uplift load capacity - provides enhanced resistance during high-wind or seismic events, making this cap well-suited for connections where lateral and uplift forces are a concern
• NDS code-compliant bolt spacing - ensures the connection meets National Design Specification requirements, supporting smooth project inspections and approvals
• Simpson Strong-Tie gray paint finish - provides a consistent, durable coating that protects the steel and complements standard structural hardware installations
• Extended seat design - distributes beam load effectively across the connection, reducing stress concentration at the end-of-beam interface

Why This Product

• Precision fit for specific lumber dimensions - designed expressly for a 6-3/4 in. beam and 4X post pairing, this cap eliminates the guesswork of sizing and ensures a secure, properly engineered connection right from the start
• Built-in resilience for high-load environments - with increased uplift load ratings for earthquake and wind loading, this end column cap is a dependable choice for structural connections that must perform under dynamic forces
• Code-ready installation - NDS-compliant bolt spacing and certified welds mean the hardware is designed to satisfy inspection requirements, reducing potential delays on the job site
• American-made quality from a recognized structural brand - produced by Simpson, a name widely specified in structural hardware, this connector is made in the United States to consistent manufacturing standards

Frequently Asked Questions

What size beam and post is the ECC74 designed to fit?

The ECC74 is designed for use with a 6-3/4" beam and a 4X post, making it suitable for structural connections where those specific lumber dimensions are required.

What fasteners are required to install the ECC74?

Installation requires 3/4" machine bolts - two for the beam connection and two for the post connection - for a total of four bolts.

Is the ECC74 suitable for use in areas prone to earthquakes or high winds?

Yes. The ECC74 features increased uplift load capacity specifically to accommodate earthquake and wind loading conditions, making it appropriate for structural connections in high-load environments.

What material and finish is the ECC74 made from?

The ECC74 is constructed from heavy-duty 3-gauge steel and finished with Simpson Strong-Tie gray paint, providing durability for demanding structural applications.
