The Simpson ECCOQ3-SDS2.5 is a 3-1/8" 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 an ideal solution for demanding structural steel applications. 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. Featuring a Quick-Install design, the ECCOQ3-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation, attaching to a greater net section area of the column than a standard bolt attachment - all without sacrificing structural integrity.

Frequently Asked Questions

What beam size is the ECCOQ3-SDS2.5 designed to fit?

The ECCOQ3-SDS2.5 is designed for use with a 3-1/8" beam, making it suitable for end-of-beam applications where a precise fit at the column-to-beam connection is required.

What does "legs omitted" mean, and how does it affect installation?

The legs-omitted design means this column cap does not include the standard legs found on conventional column caps. This allows the cap to be field-welded directly to steel columns and beams, making it well suited for structural steel applications where a welded connection is preferred or required.

What type of fasteners are used with this column cap, and why are they advantageous?

The ECCOQ3-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws for installation. These screws provide a lower profile than standard through bolts for a cleaner, more compact installation, and they attach to a greater net section area of the column compared to standard bolt attachment - all without sacrificing structural integrity.

What material and gauge steel is the ECCOQ3-SDS2.5 constructed from?

The ECCOQ3-SDS2.5 is constructed from heavy-duty 7-gauge steel, providing the strength and durability needed for demanding structural column-to-beam connection applications.
