The Simpson ECCLRQ464HDG is a hot-dip galvanized, L-shape end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Sized for a 4x main beam, 6x post, and 4x side beam configuration with the side beam oriented right, this cap helps distribute load from the beams and provides critical structural support at the connection point. Fabricated from 7-gauge steel with certified welds, it installs using included 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws for faster assembly and a lower profile than standard through-bolt connections - making it a dependable choice for exterior framing and pressure-treated lumber applications.

Key Features

• SDS screw configuration for high uplift design values - screws are strategically positioned to maximize resistance against uplift forces, helping the connection perform under demanding load conditions.
• Certified welds throughout - factory-verified weld quality gives builders confidence in the cap's structural integrity and load-carrying capacity without guesswork.
• Diamond holes for temporary fastening - allow the cap to be held in position during layout and adjustment before final installation, reducing the risk of misalignment.
• Right-side beam orientation (skewed right) - purpose-built for L-formation beam intersections where the side beam runs to the right; the ECCLLQ model is available for left-side applications, so you can match the cap to your exact framing layout.
• 7-gauge steel construction - heavy-duty material thickness provides the rigidity and strength required for structural column-to-beam connections in post-frame and timber applications.
• Hot-dip galvanized finish - provides a robust corrosion-resistant coating suited for exterior environments and direct contact with pressure-treated lumber, where standard coatings may deteriorate over time.
• Includes Strong-Drive SDS screws - the required 1/4 in. x 2-1/2 in. SDS Heavy-Duty Connector screws are included, so installation can begin without sourcing separate fasteners or substituting incompatible hardware.

Why This Product

• Purpose-built for L-formation end-of-beam connections - unlike generic post caps, this connector is specifically designed for the geometry of two beams meeting at a right-skewed angle on top of a column, reducing the need for additional brackets or braces at the joint.
• Faster installation without sacrificing strength - the included SDS screw system installs more quickly than traditional through-bolt methods and achieves a lower-profile connection, saving time on the job while maintaining high uplift design values.
• HDG coating for long-term exterior reliability - hot-dip galvanization provides a level of corrosion protection well-suited to outdoor structural applications and pressure-treated lumber contact, helping the connector maintain its integrity over the life of the structure.
• Manufactured in the United States with certified welds - domestically produced with verified weld quality, giving contractors and inspectors a consistent, traceable standard of structural performance at every connection.

Frequently Asked Questions

What member sizes is the ECCLRQ464HDG designed to fit?

This column cap is designed for a 4x main beam, a 6x post, and a 4x side beam. It is intended for end-of-beam applications where two beams intersect in an "L" formation on top of a column, generally eliminating the need for additional brackets or braces.

What fasteners are required for installation, and are they included?

This column cap installs with 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212). These screws are included with the product. The SDS screws provide faster installation and a lower profile than standard through bolts, and are configured to provide high uplift design values.

Is this column cap suitable for exterior or treated-wood applications?

Yes. The ECCLRQ464HDG features hot-dip galvanization (HDG), which offers extra corrosion resistance, making it suitable for exterior and treated-wood applications.

What is the difference between the ECCLRQ and ECCLLQ models?

The difference is the orientation of the side beam. The ECCLRQ model (this product) has the side beam oriented to the right. If you need the side beam oriented to the left, you would order the ECCLLQ model instead.
