Product Description
The Simpson Strong-Tie ECCO4/6 End Column Cap is engineered to deliver robust column-to-beam connections in end-of-beam applications on top of steel members. Designed without legs, this column cap is intended for field-welded attachment directly to steel columns and beams, making it an ideal solution for structural connections requiring precision and strength. The extended seat of the column cap provides additional bearing surface area beyond one side of the column, effectively distributing beam loads and reinforcing connection integrity. Constructed from heavy-duty 7-gauge steel and finished with Simpson Strong-Tie Gray paint, the ECCO4/6 is built to perform in demanding structural environments.
Key Features
- Legless design enables field-welded attachment to steel columns and beams

Frequently Asked Questions
- What beam width is the ECCO4/6 designed to accommodate?
- The ECCO4/6 is designed for a beam width of 3-1/2 in., with a W1 dimension of 3-5/8 in. and an overall length of 8-1/2 in., making it compatible with standard 4x lumber used in structural beam applications.
- How is the ECCO4/6 attached to steel columns and beams?
- The ECCO4/6 features a legless design that enables field-welded attachment directly to steel columns and beams. Diamond holes are also included to provide temporary fastening capability during installation before final welding is completed.
- What makes the ECCO4/6 suitable for end-of-beam applications?
- The ECCO4/6 includes an extended seat that provides additional bearing surface area beyond one side of the column, which improves load distribution and reinforces connection integrity specifically in end-of-beam positions on top of steel members.
- What material and finish does the ECCO4/6 use?
- The ECCO4/6 is constructed from heavy-duty 7-gauge steel and finished with Simpson Strong-Tie Gray paint, providing exceptional structural strength along with added protection in demanding environments.
