The Simpson 4 in Beam End Column Cap Legs Omitted Quick-Install ECCOQ4-SDS2.5 is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections on top of steel members. Its legs-omitted configuration allows for direct field-welded attachment to steel columns and beams, making it a practical solution when a traditional leg-style cap is not suitable for the application. The extended bearing seat provides additional surface area beyond the side of the column, helping to distribute load effectively and reinforce the connection where it matters most.

Key Features

• Legs-omitted design - enables field-welded attachment directly to steel columns and beams, giving installers flexibility in end-of-beam applications where standard leg attachment is not an option
• Extended bearing seat - projects beyond the side of the column to increase load-bearing surface area, delivering enhanced support and more reliable load distribution at the connection point
• Quick-Install technology with Strong-Drive SDS Heavy-Duty Connector screws - fasteners engage a greater net section area of the column than standard bolt attachment, speeding up installation while maintaining structural integrity
• Lower-profile fastener solution - Strong-Drive SDS screws sit closer to the column surface than through bolts, resulting in a cleaner, less obtrusive connection that works well in tight or finished framing conditions
• 7 gauge steel construction - provides the material strength needed to handle demanding structural loads in column-to-beam applications
• Domestic production by Simpson - built to consistent quality standards, supporting confidence in performance for structural connector applications

Why This Product

• Built for real field conditions - the legs-omitted configuration is specifically designed for scenarios where field welding to steel is required, eliminating the need to source a modified or custom connector on the job site
• Faster, cleaner installation - Quick-Install technology with included Strong-Drive SDS Heavy-Duty Connector screws means no through bolts, no extra hardware to source, and a lower-profile result that keeps framing neat and structurally sound
• Superior load distribution at the connection - the extended seat bearing area goes beyond the column edge, giving the beam more surface to bear on and reducing point-load stress at a critical structural junction
• A trusted Simpson connector made in the United States - engineered by a recognized name in structural connectors and produced domestically, this cap is a dependable choice for contractors and builders who prioritize consistent quality in column cap and beam connection hardware

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.
