The Simpson ECCOQ4.62-SDS2.5 is an End Column Cap designed to provide strong column-to-beam connections in end-of-beam applications on top of steel members. Engineered without legs, this column cap enables a field-welded attachment to steel columns and beams, making it well suited for structural connections where a clean, low-profile fastening solution is required. 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 reliable support for the connection. Installation is streamlined with included Strong-Drive SDS Heavy-Duty Connector screws, which attach to a greater net section area of the column than standard bolt attachments typically allow.

Frequently Asked Questions

What is the beam width this column cap is designed to accommodate?

The ECCOQ4.62-SDS2.5 is designed for a beam width of 41/2 in., with a W1 dimension of 4-5/8 in. (4.625 in.).

Why does this column cap have legs omitted, and how is it attached?

The legs-omitted design is intentional - it allows the column cap to be field-welded directly to steel columns and beams, making it well suited for structural connections where a clean, low-profile fastening solution is required on top of steel members.

What type of fasteners are used to install this column cap, and what advantage do they offer?

Installation uses Strong-Drive SDS Heavy-Duty Connector screws, which are included with the column cap. These screws attach to a greater net section area of the column than standard bolt attachments typically allow, and they provide a lower profile than standard through bolts. Diamond holes are also provided for temporary fastening during installation.

Can this column cap be configured for different beam and post size combinations?

Yes - many combinations of beam and post sizes can be manufactured beyond the standard configuration. If you need a different size combination, you can contact Simpson for configurable options tailored to your project requirements.
