The Simpson Strong-Tie ECC3 1/4-4HDG End Column Cap is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications within wood construction. The seat of the column cap provides an additional surface area of bearing that extends beyond one side of the column, helping to distribute load from the beam and provide solid support for the connection. Constructed from 7-gauge steel with a Hot Dip Galvanized (HDG) finish, this end column cap is built for lasting durability and corrosion resistance in demanding structural environments.

Key Features

• Certified welds for confidence in strength and loading
• Uplift loads increased for earthquake or wind loading
• Bolt spacing meets NDS code requirements to ensure optimal performance
• Diamond holes to provide temporary fastening during installation
• Hot Dip Galvanized finish for enhanced corrosion resistance
• Seat design extends bearing surface beyond one side of the column for superior load distribution

Frequently Asked Questions

What beam and post sizes is the ECC3 1/4-4HDG designed to fit?

This end column cap is designed for use with a 3-1/8" beam and a 4X post, making it suitable for standard engineered lumber and dimensional lumber applications in those sizes.

What fasteners are required to install this end column cap?

Installation requires 5/8" machine bolts - two for the beam connection and two for the post connection. The bolt spacing is designed to meet NDS code requirements for optimal performance.

Is this end column cap suitable for use in high-wind or seismic environments?

Yes. The ECC3 1/4-4HDG features increased uplift loads specifically to accommodate earthquake and wind loading conditions, making it appropriate for structural connections in seismic zones or areas subject to high-wind forces.

What material and finish does the ECC3 1/4-4HDG use, and why does it matter?

This end column cap is constructed from 7-gauge steel with a Hot Dip Galvanized (HDG) finish. The HDG finish provides enhanced corrosion resistance, making the connector well-suited for demanding structural environments where moisture or exposure could degrade standard finishes over time.
