The Simpson ECCOQ10-SDS2.5 is a 10" Beam End Column Cap with Legs Omitted, engineered to provide strong column-beam connections in end-of-beam applications on top of steel members. The column cap features a design without legs, enabling a field-welded attachment to steel columns and beams. 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 reliable support for the connection. Designed for fast installation, the ECCOQ10-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws to attach to a greater net section area of the column than a bolt attachment normally entails - making it a high-performance, time-saving solution for structural column-to-beam connections.

Installation

Fasten with 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. The legs-omitted design allows for field-welded attachment to steel columns and beams. Diamond holes are provided for temporary fastening during positioning prior to final installation.

Frequently Asked Questions

What type of fasteners are used with the ECCOQ10-SDS2.5?

The ECCOQ10-SDS2.5 is fastened using 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are included with the column cap.

Why are SDS screws used instead of standard through bolts?

The Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts and attach to a greater net section area of the column, resulting in a stronger and cleaner connection.

What does "legs omitted" mean on this column cap?

"Legs omitted" means the column cap is designed without legs, which enables field-welded attachment directly to steel columns and beams - ideal for end-of-beam applications on top of steel members.

Can the ECCOQ beam and post size combinations be customized?

Yes. Custom combinations of beam and post sizes can be manufactured for the ECCOQ10-SDS2.5. Contact Simpson Strong-Tie directly for special order configurations.
