Product Description
The Simpson ECCO9 End Column Cap is engineered to deliver strong, reliable column-beam connections in end-of-beam applications on top of steel members. Designed specifically for an 8-3/4" beam width, this column cap features a legless design that enables field-welded attachment directly to steel columns and beams. The extended seat of the column cap provides additional bearing surface area that projects beyond one side of the column, helping to distribute load from the beam and reinforce the connection. Constructed from heavy-duty 3-gauge steel and finished with Simpson Strong-Tie Gray paint, the ECCO9 is built for structural integrity and long-term performance in demanding construction environments.
Key Features

Approved Applications
- End-of-beam column-to-beam connections on top of steel members
- Field-welded connections to steel columns and beams
- Structural applications requiring enhanced uplift resistance for seismic or high-wind conditions
- Connections requiring NDS-compliant bolt spacing
- Load distribution across beam-to-column bearing surfaces in end-of-beam configurations
Installation
- Use all specified fasteners.
- Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter (per 2018 NDS, section 12.1.3.2); bolt holes should be drilled from one side all the way through the beam to maintain hole tolerances.
