The Simpson 10in Beam End Column Cap with Legs Omitted Quick-Install is a heavy-duty structural connector engineered for end-of-beam column-to-beam applications on top of steel members. Its legs-omitted design allows for field-welded attachment to steel columns and beams, while the extended bearing seat distributes load beyond the side of the column for a reliable, high-strength connection. Fastened with Strong-Drive SDS Heavy-Duty Connector screws, this cap delivers a lower-profile, faster installation compared to traditional through-bolt methods - making it a practical choice for structural framing projects where speed and connection integrity both matter.

Key Features

• Legs-omitted design - allows field-welded attachment directly to steel columns and beams, giving installers flexibility in end-of-beam connection scenarios where a standard legged cap would not fit.
• Extended bearing seat - provides additional surface area beyond the side of the column, helping to distribute beam loads more evenly and improve overall connection reliability.
• Strong-Drive SDS Heavy-Duty Connector screw fastening - attaches to a greater net section area of the column than standard through bolts, delivering high-performance holding strength with a lower-profile result.
• Diamond holes for temporary fastening - allow the cap to be held in position during layout and alignment before final installation, reducing the chance of misalignment and saving time on the job site.
• Includes fasteners - the required 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws ship with the cap, so installers have everything needed to complete the connection without sourcing hardware separately.
• 3 gauge steel construction - provides the structural rigidity expected in column-to-beam load-transfer applications, supporting dependable performance in demanding framing conditions.

Why This Product

• Designed for speed without sacrificing strength - the SDS screw-driven installation eliminates the need for drilling through-bolt holes, cutting installation time on structural steel column connections while maintaining a high-strength mechanical attachment.
• A purpose-built solution for steel-top connections - the legs-omitted configuration and field-weld compatibility make this cap specifically suited for end-of-beam scenarios on top of steel members, where a standard column cap with legs would be impractical or incompatible.
• Simplified jobsite logistics - because the required fasteners are included with the cap, crews can move directly from delivery to installation without waiting on separate hardware orders or making trips to source matching screws.
• Domestic manufacturing - the ECCOQ10-SDS2.5 is a United States-origin Simpson product, supporting consistent quality standards and traceability for projects with domestic sourcing requirements.

Installation

Fasten with 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. The legs-omitted design allows for field-welded attachment to steel columns and beams. Diamond holes are provided for temporary fastening during positioning prior to final installation.

Frequently Asked Questions

What type of fasteners are used with the ECCOQ10-SDS2.5?

The ECCOQ10-SDS2.5 is fastened using 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are included with the column cap.

Why are SDS screws used instead of standard through bolts?

The Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts and attach to a greater net section area of the column, resulting in a stronger and cleaner connection.

What does "legs omitted" mean on this column cap?

"Legs omitted" means the column cap is designed without legs, which enables field-welded attachment directly to steel columns and beams - ideal for end-of-beam applications on top of steel members.

Can the ECCOQ beam and post size combinations be customized?

Yes. Custom combinations of beam and post sizes can be manufactured for the ECCOQ10-SDS2.5. Contact Simpson Strong-Tie directly for special order configurations.
