The Simpson 5-1/8" Beam End Column Cap Legs Omitted Quick-Install ECCOQ5-SDS2.5 is a heavy-duty structural connector built for end-of-beam column-to-beam connections on top of steel members. With legs omitted by design, this column cap is intended for field-welded attachment to steel columns and beams, making it a practical choice for structural applications where standard leg configurations are not feasible. Quick-Install technology via Strong-Drive SDS Heavy-Duty Connector screws delivers a lower-profile fastening solution compared to standard through-bolt connections, helping crews work more efficiently without sacrificing connection integrity.

Key Features

• Legs-omitted configuration - allows field-welded attachment directly to steel columns and beams, expanding the range of structural connections where a traditional leg design would not be practical
• Designed for end-of-beam applications on top of steel members - provides a purpose-built solution for column-to-beam connections at beam ends, ensuring proper load transfer in these specific structural situations
• Quick-Install technology with Strong-Drive SDS Heavy-Duty Connector screws - replaces standard through bolts to produce a cleaner, lower-profile installation and reduce time on the job
• Extended seat bearing surface - the seat of the column cap reaches beyond the side of the column to help distribute beam load and support the connection at the bearing point
• 3 gauge steel construction - delivers the material strength needed for demanding structural column cap applications
• Domestic production - manufactured in the United States, supporting consistent quality standards expected from Simpson structural connectors

Why This Product

• Engineered for steel-column applications where standard caps fall short - the legs-omitted design makes field-welded attachment to steel possible, opening up connection options that a conventional column cap with legs simply cannot accommodate
• Faster installation without compromising the connection - Strong-Drive SDS Heavy-Duty Connector screws are included and replace traditional through-bolt fastening, cutting installation steps and leaving a lower-profile, cleaner result
• Built for reliable load distribution at beam ends - the extended seat bearing surface provides critical support beyond the column face, helping structural loads transfer properly in end-of-beam column cap applications
• A trusted Simpson connector made in the United States - backing a structural connection with a Simpson product means specifiers and installers can count on the brand recognition and quality association that the Simpson name carries in connector hardware

Frequently Asked Questions

What does "legs omitted" mean on the ECCOQ5-SDS2.5, and why does it matter?

A legs-omitted design means the column cap does not include the standard leg extensions found on conventional column caps. This allows the connector to be field-welded directly to steel columns and beams, making it a practical solution for structural connections where traditional leg configurations are not feasible or practical.

How does the Quick-Install feature work on this column cap?

The Quick-Install feature uses Strong-Drive SDS Heavy-Duty Connector screws instead of standard through bolts. This approach results in a lower profile installation, a cleaner appearance, and faster assembly. The SDS screws also attach to a greater net section area of the column than bolt attachment normally allows.

What is the purpose of the extended seat bearing surface on the ECCOQ5-SDS2.5?

The seat of the column cap extends beyond the side of the column, providing additional surface area for bearing. This helps distribute the load from the beam and provides critical support for the connection, which is especially important in end-of-beam applications on top of steel members.

Can this column cap be configured for different beam and post sizes?

Yes. While the ECCOQ5-SDS2.5 is sized for a 5-1/8" beam, many combinations of beam and post sizes can be manufactured. If your project requires a different configuration, you can contact Simpson for configurable options tailored to your specific application.
