The Simpson ECCOQ4-SDS2.5 is a 4" Beam End Column Cap with Legs Omitted, engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications on top of steel members. Designed without legs, this column cap enables field-welded attachment directly to steel columns and beams for a streamlined, structurally sound installation. The seat of the column cap provides additional surface area for bearing that extends beyond the side of the column, helping to distribute load from the beam and provide critical support for the connection. Featuring Quick-Install technology via Strong-Drive SDS Heavy-Duty Connector screws, the ECCOQ4-SDS2.5 attaches to a greater net section area of the column than a standard bolt attachment - all while maintaining a lower profile for cleaner, more efficient assemblies.

Frequently Asked Questions

What makes the ECCOQ4-SDS2.5 different from a standard column cap?

The ECCOQ4-SDS2.5 features a legs-omitted design, which allows it to be field-welded directly to steel columns and beams rather than relying on a traditional leg attachment. It also uses Quick-Install technology with Strong-Drive SDS Heavy-Duty Connector screws, which attach to a greater net section area of the column compared to standard bolt attachment and maintain a lower profile than through bolts.

What type of fasteners are used to install this column cap?

This column cap installs using Strong-Drive SDS Heavy-Duty Connector screws. These screws provide a lower profile than standard through bolts and engage a greater net section area of the column, contributing to a stronger and cleaner connection.

Does the ECCOQ4-SDS2.5 include any features to assist with temporary positioning during installation?

Yes, the ECCOQ4-SDS2.5 includes diamond holes that allow for temporary fastening during installation, making it easier to hold the connector in position while completing the final attachment.

Can this column cap accommodate different beam and post sizes?

Yes, many combinations of beam and post sizes can be manufactured for this product. If your project requires a specific configuration beyond the standard 4" beam end application, you can contact Simpson for configurable options tailored to your needs.
