The Simpson Strong-Tie ECC5 1/4-5 1/4 End Column Cap is an engineered connector designed to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. Engineered for structural integrity, the ECC features a seat that extends beyond one side of the column, providing an expanded bearing surface area that effectively distributes beam loads and delivers critical support at the connection point. Ideal for demanding structural applications where uplift resistance, bolt code compliance, and certified weld strength are essential, the ECC5 1/4-5 1/4 is purpose-built for 5-1/8" beams and 5-1/8" posts.

Key Features

• Certified Welds: Certified welds for confidence in strength and loading
• Enhanced Uplift Resistance: Uplift loads increased for earthquake or wind loading
• Code-Compliant Bolt Spacing: Bolt spacing that meets NDS code requirements to ensure optimal performance
• Diamond Holes: Diamond holes to provide temporary fastening during installation
• Extended Bearing Surface: Seat of the column cap provides additional surface area of bearing that extends beyond one side of the column
• Load Distribution: Helps distribute the load from the beam and provide support for the connection

Frequently Asked Questions

What beam and post sizes is the ECC5 1/4-5 1/4 designed to fit?

This end column cap is purpose-built for use with 5-1/8" beams and 5-1/8" posts, making it specifically suited to glulam or engineered lumber members of those dimensions.

What fasteners are required to install the ECC5 1/4-5 1/4?

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

What features make this connector suitable for use in high-wind or seismic zones?

The ECC5 1/4-5 1/4 includes enhanced uplift resistance with uplift loads increased for earthquake or wind loading, certified welds for confirmed strength, and bolt spacing that meets NDS code requirements - all of which contribute to reliable performance in demanding structural conditions.

What material and finish does the ECC5 1/4-5 1/4 have?

The connector is made from 3 gauge steel and finished with Simpson Strong-Tie gray paint, providing a durable surface suitable for typical wood construction environments.
