The Simpson Strong-Tie ECCLLQ444SDS L-Shape End Column Cap is 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 supporting post or column. Built for nominal 4x main beam, 4x post, and 4x side beam members, this left-skew column cap helps distribute load from intersecting beams and provides critical structural support at the connection point - generally eliminating the need for additional brackets or braces. Strong-Drive SDS Heavy-Duty Connector screws are included, enabling faster installation and a lower profile compared to standard through bolts.

Key Features

• SDS screws configured for high uplift design values - fastener placement is optimized to resist uplift forces, giving builders confidence in the connection's structural performance under load.
• Certified welds throughout the cap - weld quality is independently verified, so you can trust the connector's strength and load capacity without guesswork.
• Diamond holes for temporary fastening - allow the cap to be held securely in position during alignment before final fastening, making installation easier and more accurate.
• Left-side beam orientation - specifically designed for L-shaped end column connections where the side beam is oriented to the left; the ECCLRQ model is available for right-side beam orientation.
• 7-gauge steel construction - heavy-gauge material provides the rigidity and strength required for demanding structural framing applications such as decks and pergolas.
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and baseline protection suited for structural connector applications.
• Includes 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws - everything needed for installation arrives with the cap, reducing trips to the hardware store and ensuring the correct fasteners are used for rated load values.

Why This Product

• A purpose-built solution for L-shaped beam intersections - rather than adapting a generic connector, this cap is specifically designed for end-of-beam applications where a main beam and side beam meet at an "L" formation over a post, making it the right tool for the job from the start.
• Faster installation without sacrificing load performance - Strong-Drive SDS screws replace the need for through bolts, cutting installation time and delivering a lower-profile connection while maintaining high uplift design values.
• Confidence in every weld and fastener - certified welds and a screw configuration optimized for uplift resistance mean this connector is built and verified to perform, not just assembled and shipped.
• Fits common 4x lumber across all three members - compatibility with 4x nominal sizing for the main beam, side beam, and post means this cap integrates cleanly into standard deck, pergola, and structural framing projects without custom modifications.

Frequently Asked Questions

What member sizes is the ECCLLQ444SDS compatible with?

This column cap is designed for nominal member sizes of a 4x main beam, 4x post, and 4x side beam, making it suitable for end-of-beam applications where two beams intersect in an "L" formation on top of a column.

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

The ECCLLQ444SDS installs with 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212), which are included with the product. These screws provide faster installation and a lower profile than standard through bolts.

What is the difference between the ECCLLQ444SDS and the ECCLRQ model?

The ECCLLQ444SDS features a side beam oriented to the left. If your project requires a right-side beam orientation, you should order the ECCLRQ model instead.

What material and finish is this column cap made from?

The ECCLLQ444SDS is constructed from 7-gauge steel and features a Simpson Strong-Tie gray paint finish. It also includes certified welds for confidence in strength and load-bearing performance.
