The Simpson Strong-Tie ECCLLQ3.25-6SDS L-Shape End Column Cap is engineered for end-of-beam applications where two beams intersect in an "L" formation on top of a column, delivering a strong, dependable column-to-beam connection without the need for additional brackets or braces. Built from 7-gauge steel with a Simpson Strong-Tie gray paint finish, this left-skewed cap accepts a 3-1/4 in. main beam, a nominal 6x post, and a 3-1/4 in. side beam, making it a purpose-built solution for structural beam-to-post connections that demand high uplift resistance. Strong-Drive SDS Heavy-Duty Connector screws are included, enabling faster installation and a lower profile than standard through bolts.

Key Features

• SDS screw fastening pattern configured for high uplift design values - reduces the risk of connection failure under uplift loads, giving builders confidence in structural performance.
• Certified welds throughout the cap - provides verified strength and load capacity at every welded joint, so the connection integrity is not left to guesswork.
• Diamond holes for temporary fastening - allows the cap to be positioned and held in place during layout before final installation, simplifying the assembly process.
• Left-side beam orientation - purpose-built for L-formation connections where the side beam runs to the left; the right-oriented ECCLRQ model is available when the opposite configuration is needed.
• 7-gauge steel construction - delivers heavy-duty strength suited for demanding structural column cap applications.
• Strong-Drive SDS Heavy-Duty Connector screws included - eliminates a separate fastener purchase and ensures the correct hardware is on hand for proper installation from the start.
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance while offering a baseline level of surface protection for the steel connector.

Why This Product

• A complete, ready-to-install connection solution - the cap ships with the required Strong-Drive SDS Heavy-Duty Connector screws already included, so the correct fasteners are matched to the connector without any additional sourcing.
• Engineered specifically for L-formation end-of-beam connections - rather than adapting a general-purpose bracket, this cap is designed from the ground up for the exact geometry of two intersecting beams atop a column, supporting proper load distribution across the connection.
• Lower-profile installation compared to standard through bolts - the SDS screw-based fastening system keeps the connection tight and clean without the bulk of traditional bolted hardware, a practical advantage in finish-sensitive or space-constrained framing situations.
• Certified welds and high-uplift screw configuration work together - both the welded fabrication and the fastener layout are engineered to work as a system, providing structural reliability for beam-to-post connections where uplift resistance is a key design requirement.
