The Simpson Strong-Tie ECC5 1/4-6HDG End Column Cap is an engineered steel connector designed to deliver strong, reliable column-to-beam connections in end-of-beam applications for wood construction. The seat of the column cap provides an additional bearing surface area that extends beyond one side of the column, effectively distributing load from the beam and providing critical structural support at the connection point. Built from heavy-gauge steel with a hot dip galvanized finish, the ECC5 1/4-6HDG is purpose-built for demanding structural environments where corrosion resistance and load-bearing performance are essential.

Key Features

• Certified Welds - Engineered with certified welds for confidence in strength and loading capacity
• Enhanced Uplift Loads - Uplift loads increased to meet the demands of earthquake or wind loading conditions
• NDS-Compliant Bolt Spacing - Bolt spacing meets NDS code requirements to ensure optimal structural performance
• Diamond Holes - Diamond holes provide convenient temporary fastening during installation
• Heavy-Gauge Construction - Fabricated from 3-gauge steel for robust load transfer
• Hot Dip Galvanized Finish - Provides superior corrosion resistance for exposed or treated-lumber applications
• Extended Bearing Surface - Seat design extends beyond one side of the column to maximize load distribution

Frequently Asked Questions

What beam and post sizes is the ECC5 1/4-6HDG designed for?

The ECC5 1/4-6HDG is designed for use with a 5-1/8" beam and a 6X post, making it suitable for standard engineered lumber and dimensional lumber framing configurations.

What fasteners are required to install this column cap?

Installation requires 3/4" machine bolts - two for the beam connection and two for the post connection. Fasteners are not included and must be sourced separately.

Why is a hot dip galvanized finish specified for this connector?

The hot dip galvanized (HDG) finish provides a thick, durable zinc coating that offers superior protection against corrosion, making it appropriate for outdoor, high-moisture, or treated-lumber environments where standard zinc finishes may be insufficient.
