The Simpson Strong-Tie ECCOQ6-SDS2.5 is a 6-inch beam end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications positioned on top of steel members. Designed with legs omitted, this column cap enables field-welded attachment directly to steel columns and beams, providing a clean, low-profile connection solution. The extended seat design provides additional surface area for bearing beyond the side of the column, helping to effectively distribute load from the beam and deliver superior support at the connection point. Fastened with included 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, the ECCOQ6-SDS2.5 offers quick, efficient installation while engaging a greater net section area of the column compared to standard bolt attachments.

Frequently Asked Questions

Why does this column cap have legs omitted, and how does it attach to steel?

The legs-omitted design allows the ECCOQ6-SDS2.5 to be field-welded directly to steel columns and beams, making it well-suited for end-of-beam applications where the cap sits on top of a steel member. This approach provides a clean, low-profile connection without the need for pre-formed legs.

What fasteners are used to install this column cap, and are they included?

The ECCOQ6-SDS2.5 is fastened with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws offer a lower profile than standard through bolts and attach to a greater net section area of the column than a bolt attachment normally provides.

What is the extended seat feature, and what benefit does it provide?

The extended seat is designed to provide additional bearing surface area beyond the side of the column. This helps distribute the load from the beam more effectively, delivering improved support at the connection point compared to a standard seat configuration.

What material and gauge of steel is the ECCOQ6-SDS2.5 constructed from?

The ECCOQ6-SDS2.5 is constructed from 7-gauge steel, which provides heavy-duty structural performance suited for demanding column-to-beam connection applications.
