The Simpson ECCOQ7-SDS2.5 is a 6-3/4" 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 a field-welded attachment to steel columns and beams, making it a purpose-built solution for structural steel construction. 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. Fastened with Strong-Drive SDS Heavy-Duty Connector screws, the ECCOQ7-SDS2.5 delivers fast, high-performance installation while attaching to a greater net section area of the column than a standard bolt attachment normally entails.

Key Features

• No-Leg Design: Enables field-welded attachment directly to steel columns and beams for end-of-beam applications
• Extended Bearing Seat: The seat provides additional surface area that extends beyond the side of the column, helping to distribute beam load and support the connection
• Strong-Drive SDS Screws: Provides a lower profile than standard through bolts while attaching to a greater net section area of the column
• Diamond Holes: Included for convenient temporary fastening during installation
• Quick-Install Design: SDS Heavy-Duty Connector screws enable fast, efficient field installation
• Heavy-Duty 3-Gauge Steel Construction: Built to handle demanding structural connection requirements
• Many Combinations Available: Many combinations of beam and post sizes can be manufactured - Contact us for configurable options and special orders

Frequently Asked Questions

What type of fasteners are used with the ECCOQ7-SDS2.5?

The ECCOQ7-SDS2.5 is fastened with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are included with the column cap.

Why are SDS screws preferred over standard through bolts for this application?

The SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a bolt attachment normally entails, improving both aesthetics and structural performance.

What does "Legs Omitted" mean for this column cap?

The legs-omitted design means the column cap does not include legs, enabling a field-welded attachment to steel columns and beams - making it ideal for end-of-beam applications on top of steel members.

Are custom beam and post size combinations available?

Yes. Custom combinations of beam and post sizes can be manufactured for the ECCOQ7-SDS2.5. Contact Simpson Strong-Tie directly for special order configurations.
