The Simpson ECCQ4.62-5.50HDG End Column Cap is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications in wood construction. Sized for a triple 2x beam and 6x post, this heavy-duty connector features an extended seat that provides additional bearing surface area beyond the side of the column, helping to distribute load from the beam and reinforce the overall connection. Built from 7-gauge steel with a hot-dip galvanized finish, it is well-suited for exterior structural applications and connections involving pressure-treated lumber where corrosion resistance is critical. Simpson column caps come in a variety of sizes to accommodate virtually any project, generally eliminating the need for additional brackets or braces - and the ECCQ uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation while attaching to a greater net section area of the column than a bolt attachment normally entails.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - 28 screws (14 for beam, 14 for post) are included in the box, so you have everything needed for a complete installation without sourcing fasteners separately.
• Lower-profile SDS screw attachment - SDS screws sit with a lower profile than standard through bolts, resulting in a cleaner, less obtrusive connection on finished structural work.
• Extended seat bearing surface - the seat extends beyond the side of the column, distributing load from the beam more effectively and providing additional support at the connection point.
• Certified welds - weld quality is certified, giving you verifiable confidence in the strength and load capacity of the connector.
• Increased uplift load ratings - uplift loads have been increased for earthquake or wind loading, making this cap appropriate for structural applications in high-wind or seismic zones.
• Diamond holes for temporary fastening - allows you to tack the cap in place during positioning before driving final fasteners, improving installation accuracy.
• 7-gauge steel construction - heavy-gauge material provides the structural rigidity required for demanding column-to-beam connections in wood construction.
• Hot-dip galvanized coating - HDG finish offers extra corrosion resistance compared to standard coatings, making this connector suitable for exterior use and applications involving pressure-treated lumber.

Why This Product

• A complete, ready-to-install connection solution - the cap ships with all 28 required Strong-Drive SDS screws already included, eliminating a separate trip to source compatible fasteners and keeping your project moving.
• Built for end-of-beam applications where standard caps fall short - the extended seat bearing surface is specifically designed for end-of-beam column-to-beam connections, providing load distribution and support that a standard cap without this feature would not offer.
• Rated for high-wind and seismic conditions - increased uplift load capacity means this connector meets the demands of projects in zones where wind or earthquake forces are a design consideration, without requiring supplemental hardware.
• Hot-dip galvanized for long-term performance in harsh environments - the HDG finish is specifically suited for exterior structural applications and pressure-treated lumber connections where standard coatings can deteriorate prematurely, helping protect the integrity of the connection over time.
