The Simpson ECC5 1/4-4 End Column Cap is an engineered steel connector from Simpson built for end-of-beam column-to-beam connections in wood construction. Designed specifically for a 5-1/8 in. beam and a 4X post, this column cap extends bearing area beyond one side of the column to help distribute load from the beam to the post, making it a dependable choice for structural framing applications subject to gravity, wind, or seismic uplift demands.

Key Features

• Extended bearing seat design - provides additional surface area beyond one side of the column, improving load distribution from beam to post at end-of-beam locations
• Certified welds - gives builders and inspectors confidence in connection strength and load capacity without guesswork
• Increased uplift load capacity - engineered to meet the demands of earthquake and high-wind loading scenarios, keeping connections secure under lateral and uplift forces
• NDS-compliant bolt spacing - bolt layout meets National Design Specification requirements, supporting smooth project inspections and code-compliant framing
• 3 gauge steel construction with Simpson Strong-Tie gray paint finish - delivers a robust, corrosion-resistant connector suited for demanding structural environments
• Fits standard 5-1/8 in. engineered lumber and 4X dimensional post - compatible with common beam and post sizes used in timber and heavy wood framing, reducing the need for custom fabrication

Why This Product

• Purpose-built for end-of-beam applications - the ECC5 1/4-4 is specifically designed for column cap connections at the end of a beam run, addressing a structural condition that general connectors are not optimized for
• Engineered for high-demand structural loads - with increased uplift capacity and certified welds, this connector is a practical solution for projects in seismic zones or high-wind regions where connection performance is critical
• Domestic manufacturing - produced in the United States, supporting consistent quality standards for structural hardware used in load-bearing framing
• Configurable for non-standard lumber - straps may be rotated 90 deg. and an optional W2 dimension can be specified, offering flexibility for rough-cut or non-standard lumber sizes without sourcing a completely different connector

Frequently Asked Questions

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

The ECC5 1/4-4 is designed for use with a 5-1/8" beam and a 4X post, making it compatible with standard engineered lumber and dimensional lumber in those sizes for end-of-beam column-to-beam connections.

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

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 material and finish is used on the ECC5 1/4-4?

The ECC5 1/4-4 is constructed from 3 gauge steel and features a Simpson Strong-Tie gray paint finish, which provides corrosion resistance and durability for demanding structural applications.

Is the ECC5 1/4-4 suitable for use in high-wind or seismic load conditions?

Yes, the ECC5 1/4-4 features increased uplift load capacity to meet the demands of earthquake or wind loading scenarios, and its certified welds and bolt spacing that meets NDS code requirements make it well suited for structurally demanding conditions.
