The Simpson 3-1/8 in. Beam End Column Cap with Legs Omitted is built for end-of-beam column-to-beam connections on top of steel members, delivering a clean, low-profile solution where conventional column caps with legs are not suitable. The legs-omitted configuration allows for field-welded attachment directly to steel columns and beams, making this cap a reliable choice for demanding structural steel applications. The seat of the cap extends beyond the side of the column to provide additional bearing surface area, helping to distribute load effectively at the connection point.

Key Features

• Legs-omitted profile - allows field-welded attachment to steel columns and beams, giving structural teams the flexibility needed where standard legged caps cannot be used
• Quick-Install design using Strong-Drive SDS Heavy-Duty Connector Screws - fasteners attach to a greater net section area of the column compared to standard bolt attachment, speeding up installation without sacrificing connection integrity
• Extended seat bearing surface - the seat reaches beyond the side of the column, distributing beam load more effectively and providing critical support at the end-of-beam connection
• 7-gauge steel construction - provides the structural strength and durability required for load-bearing column-to-beam applications in steel framing projects
• Fits a 3-1/8 in. beam - precision-sized for an accurate, secure fit at the column-to-beam interface, eliminating guesswork during installation

Why This Product

• Engineered for steel-to-steel connections - the legs-omitted design paired with field-weld compatibility makes this cap purpose-built for structural steel applications where a welded connection is preferred or required, reducing the need for workarounds on the job site
• Faster fastening without compromise - the Quick-Install system relies on Strong-Drive SDS Heavy-Duty Connector Screws that engage a greater net section area of the column than a standard bolt, meaning structural contractors gain installation speed while maintaining a high-integrity connection
• Enhanced load distribution at the bearing point - the extended seat surface area beyond the column side is a design detail that directly benefits load transfer, making this cap well suited for end-of-beam applications where bearing performance matters
• American-made Simpson quality - produced in the United States, this column cap carries the trusted Simpson engineering reputation that structural professionals rely on for precision-fit hardware in code-sensitive applications

Frequently Asked Questions

What beam size is the ECCOQ3-SDS2.5 designed to fit?

The ECCOQ3-SDS2.5 is designed for use with a 3-1/8" beam, making it suitable for end-of-beam applications where a precise fit at the column-to-beam connection is required.

What does "legs omitted" mean, and how does it affect installation?

The legs-omitted design means this column cap does not include the standard legs found on conventional column caps. This allows the cap to be field-welded directly to steel columns and beams, making it well suited for structural steel applications where a welded connection is preferred or required.

What type of fasteners are used with this column cap, and why are they advantageous?

The ECCOQ3-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws for installation. These screws provide a lower profile than standard through bolts for a cleaner, more compact installation, and they attach to a greater net section area of the column compared to standard bolt attachment - all without sacrificing structural integrity.

What material and gauge steel is the ECCOQ3-SDS2.5 constructed from?

The ECCOQ3-SDS2.5 is constructed from heavy-duty 7-gauge steel, providing the strength and durability needed for demanding structural column-to-beam connection applications.
