The Simpson ECC44HDG End Column Cap is engineered by Simpson to deliver strong, reliable column-beam connections in end-of-beam applications throughout 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 the load from the beam and provide support for the connection. Constructed from 7-gauge steel with a hot-dip galvanized finish, this end column cap is built to hold up in exterior environments and where contact with treated wood demands heightened corrosion resistance.

Key Features

• Certified welds - provide confidence in strength and loading so builders can trust the integrity of every connection.
• Increased uplift load capacity - supports earthquake and wind loading requirements, making this cap appropriate for high-demand structural applications.
• Bolt spacing that meets NDS code requirements - ensures optimal performance and simplifies the inspection and approval process on the job site.
• Diamond holes for temporary fastening - allow for quick positioning and hands-free alignment during installation, saving time before final bolting.
• Designed for nominal 4x beam and 4x post members - fits standard dimensional lumber so there is no guesswork when selecting hardware for common framing configurations.
• 7-gauge steel construction - delivers the structural thickness needed to handle heavy column-to-beam load transfer in demanding applications.
• Hot-dip galvanized coating - offers extra corrosion resistance for exterior and treated-wood applications where standard coatings fall short over time.

Why This Product

• Built for end-of-beam post-to-beam connections - the extended bearing seat distributes beam loads beyond one side of the column, addressing a structural challenge that standard column caps are not designed to solve.
• Hot-dip galvanization for long-term durability - HDG coating provides a higher level of corrosion resistance than standard finishes, making this cap a dependable choice for outdoor decks, pergolas, and other exposed wood framing where moisture and treated lumber accelerate corrosion.
• Code-compatible design with certified welds - bolt spacing meets NDS code requirements and certified welds back up the load ratings, reducing friction during permitting and giving contractors confidence in the connection's performance.
• Engineered for seismic and wind uplift demands - increased uplift load values make this end column cap a practical choice in regions where earthquake or high-wind design criteria govern the structural connection requirements.

Frequently Asked Questions

What is the ECC44HDG designed to do?

The ECC44HDG End Column Cap is designed to provide strong column-beam connections in end-of-beam applications in 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 the load from the beam and support the connection.

What lumber sizes does the ECC44HDG fit?

The ECC44HDG is designed for a nominal 4x beam width and a nominal 4x post size, making it compatible with standard 4x dimensional lumber members.

Why is the hot-dip galvanized finish important?

Hot-dip galvanization (HDG) provides extra corrosion resistance, making the ECC44HDG suitable for exterior applications and use with treated wood where standard finishes may not offer adequate protection against the elements or chemical exposure.

Is the ECC44HDG rated for seismic and high-wind conditions?

Yes. The ECC44HDG features uplift loads increased for earthquake or wind loading, along with certified welds and bolt spacing that meets NDS code requirements, ensuring the connector performs reliably under demanding structural conditions.
