The Simpson Strong-Tie ECC5 1/4-6PC End Column Cap is engineered to deliver reliable column-to-beam connections in end-of-beam applications throughout wood construction. Designed with a seat that extends beyond one side of the column, this black powder-coated steel cap provides an additional surface area of bearing to effectively distribute load from the beam while providing critical support at the connection point. Built from heavy-duty 3-gauge steel with certified welds, the ECC5 1/4-6PC is purpose-built for demanding structural applications where strength, code compliance, and durability are essential.

Key Features

• Certified welds for confidence in strength and loading
• Uplift loads increased for earthquake or wind loading resistance
• Bolt spacing that meets NDS code requirements to ensure optimal performance
• Diamond holes to provide temporary fastening during installation
• Seat design provides additional bearing surface area extending beyond one side of the column
• Distributes load from the beam and supports the column-beam connection
• Black powder-coat finish for corrosion resistance and a clean aesthetic

Frequently Asked Questions

What beam and post size is the ECC5 1/4-6PC designed for?

The ECC5 1/4-6PC is specifically designed for a 5-1/8" beam paired with a 6X post, making it suitable for timber-frame and heavy wood construction applications requiring that lumber dimension combination.

What fasteners are required to install this end column cap?

Installation requires 3/4" Machine Bolts - two (2) for the beam connection and two (2) for the post connection. Fasteners are not included with the cap and must be sourced separately.

Is the ECC5 1/4-6PC suitable for high-wind or seismic zones?

Yes. The ECC5 1/4-6PC features increased uplift load capacity specifically to accommodate earthquake and wind loading demands, making it appropriate for use in seismic and high-wind design applications.

Where is the ECC5 1/4-6PC manufactured?

This product is manufactured in the United States.
