The Simpson ECCOQ5-SDS2.5 is a 5-1/8" Beam End Column Cap with Legs Omitted, engineered to deliver strong, reliable column-beam connections in end-of-beam applications on top of steel members. Designed without legs, this column cap enables field-welded attachment to steel columns and beams, making it a versatile solution for structural connections where traditional leg configurations are not practical. The seat of the column cap provides additional surface area for bearing that extends beyond the side of the column, helping to distribute the load from the beam and provide critical support for the connection. Featuring Quick-Install technology via Strong-Drive SDS Heavy-Duty Connector screws, the ECCOQ5-SDS2.5 delivers a faster, cleaner installation with a lower profile than standard through-bolt methods - all while attaching to a greater net section area of the column.

Key Features

• Legs-omitted design enables field-welded attachment to steel columns and beams
• Extended seat bearing surface reaches beyond the side of the column to help distribute beam loads and support the connection
• Quick-Install SDS screws provide a lower profile than standard through bolts for a cleaner, faster installation
• Diamond holes for convenient temporary fastening during positioning
• SDS screws attach to a greater net section area of the column than bolt attachment normally allows
• Many combinations of beam and post sizes can be manufactured - Contact us for configurable options
• Made in the United States

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.
