The Simpson End Column Cap for 6x Post and 10x Beam is engineered by Simpson to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. The extended seat design distributes beam loads beyond one side of the column, providing robust support at the connection point and making this cap a dependable choice for heavy timber structural assemblies where performance under load is critical.

Key Features

• Extended seat design - distributes beam load beyond one side of the column, reducing stress concentration and improving overall connection integrity in end-of-beam installations
• Increased uplift load capacity - engineered to resist elevated uplift forces associated with earthquake and high-wind loading, giving builders confidence in demanding structural applications
• Certified welds - provide assurance of connection strength and load performance, supporting structural reliability throughout the life of the assembly
• Bolt spacing that meets NDS code requirements - helps projects achieve compliance without additional field calculations or hardware modifications
• Diamond holes for temporary fastening - allow the cap to be held securely in position during layout and alignment, simplifying the installation process before final bolting
• 3 gauge steel construction with Simpson gray paint finish - delivers the material thickness and corrosion-resistant coating expected for exposed or semi-exposed structural connections in wood framing

Why This Product

• Purpose-built for end-of-beam column cap applications - the ECC106 is specifically designed for 10x beam and 6x post combinations, so structural professionals get a connector sized and rated for the exact connection rather than an adapted general-purpose bracket
• Engineered for code-sensitive structural environments - with NDS-compliant bolt spacing and increased uplift resistance for seismic and wind loading, this connector is well suited for projects where code compliance and load documentation matter
• Made in the United States by Simpson - a brand widely trusted in structural wood construction for consistent manufacturing standards and connector engineering
• Configurable for non-standard lumber dimensions - straps may be rotated 90 deg. and custom sizing options are available for special or rough-cut lumber, making this cap adaptable beyond standard dimensional lumber jobsites

Frequently Asked Questions

What lumber sizes is the ECC106 designed to work with?

The ECC106 is designed for use with a 10X beam and a 6X post, making it suitable for heavy timber end-of-beam column cap applications in wood construction.

What fasteners are required to install the ECC106?

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

Does the ECC106 provide resistance to earthquake and wind uplift forces?

Yes. The ECC106 features increased uplift load capacity specifically to address the demands of earthquake and wind loading conditions in structural applications.

How does the ECC106 seat design benefit load distribution?

The seat of the column cap provides additional surface area of bearing that extends beyond one side of the column, helping to distribute the load from the beam more effectively and provide enhanced support at the connection.
