The Simpson Strong-Tie ECCLLQ3.25-4SDS is an L-Shape End Column Cap engineered to deliver strong, reliable column-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Designed for a 3-1/4 in. main beam, 3-1/4 in. side beam, and nominal 4x post, this left-oriented column cap helps distribute load from the beams and provides critical structural support at the connection point. Constructed from heavy-duty 7-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, the ECCLLQ3.25-4SDS is built for lasting performance and confidence in both strength and loading. Installation is streamlined using included Strong-Drive SDS Heavy-Duty Connector screws, which deliver a faster, lower-profile alternative to standard through bolts while achieving high uplift design values. Simpson Strong-Tie column caps come in a variety of sizes to accommodate virtually any project, generally eliminating the need for additional brackets or braces.

Key Features

• High Uplift Design Values: Screws are configured to provide high uplift design values for demanding structural applications.
• Certified Welds: Certified welds deliver confidence in strength and loading performance.
• Diamond Holes: Diamond holes allow for temporary fastening during installation, simplifying the assembly process.
• Left-Side Beam Orientation: Side beam is oriented left; order the ECCLRQ model for right-side beam orientation.
• 7-Gauge Steel Construction: Made from 7-gauge steel for heavy-duty structural integrity.
• Gray Paint Finish: Simpson Strong-Tie gray paint finish provides a clean, professional appearance.
• SDS Screw Installation: Uses Strong-Drive SDS Heavy-Duty Connector screws for faster installation and a lower profile than standard through bolts.
• No Additional Brackets Needed: Sized to accommodate the connection, generally eliminating the need for additional brackets or braces.
• Made in the United States

Frequently Asked Questions

What member sizes is the ECCLLQ3.25-4SDS designed to fit?

This column cap is designed for a 3-1/4 in. main beam, a 3-1/4 in. side beam, and a nominal 4x post.

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

This column cap installs using 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 compared to standard through bolts.

What is the difference between the ECCLLQ and ECCLRQ models?

The ECCLLQ model, which includes this ECCLLQ3.25-4SDS, is configured with the side beam oriented to the left. If you need the side beam oriented to the right, you should order the ECCLRQ model instead.

What materials and finish does this column cap feature?

The ECCLLQ3.25-4SDS is constructed from 7-gauge steel with certified welds and is finished with a Simpson Strong-Tie gray paint coating. The certified welds are designed to provide confidence in both strength and loading performance.
