The Simpson Strong-Tie ECCO8 is an 8x beam end column cap engineered to deliver robust column-to-beam connections in end-of-beam applications on top of steel members. With a legless design, the ECCO8 is built for field-welded attachment directly to steel columns and beams, making it an ideal solution where traditional leg-style caps are not suitable. The extended seat provides additional bearing surface area beyond one side of the column, effectively distributing beam loads and delivering reliable structural support at critical connection points. Fabricated from heavy-duty 3-gauge steel with a Simpson Strong-Tie Gray paint finish, the ECCO8 is a dependable choice for demanding structural applications.
Key Features
-
Legless Column Cap Design: Enables field-welded attachment to steel columns and beams without the need for pre-installed legs, offering flexibility in end-of-beam installations.
-
Extended Seat Bearing Surface: The seat extends beyond one side of the column to maximize load distribution from the beam and enhance connection support.
-
Increased Uplift Load Capacity: Engineered to handle elevated uplift loads associated with earthquake or wind loading conditions.
-
NDS Code-Compliant Bolt Spacing: Bolt spacing meets National Design Specification (NDS) code requirements to ensure optimal structural performance.
-
Diamond Holes for Temporary Fastening: Integrated diamond holes allow for convenient temporary fastening during installation.
-
Heavy-Gauge Steel Construction: Built from 3-gauge steel for maximum strength and durability in structural applications.
-
Simpson Strong-Tie Gray Paint Finish: Factory-applied gray paint finish provides a clean, consistent appearance and surface protection.

Approved Applications
- End-of-beam column-to-beam connections on top of steel members
- Field-welded connections to steel columns and beams where legs are not required
- Structural applications requiring enhanced uplift resistance for seismic or high-wind loading
- Connections involving pipe columns or other non-standard steel column profiles (weld by designer)
- Applications requiring NDS code-compliant bolt spacing for beam connections
Installation Notes
- Use all specified fasteners as outlined in the product specifications.
- 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.
- Contact engineered wood manufacturers for connections involving engineered wood products.
- Field welding to steel columns and beams to be performed by a qualified designer or installer.

Frequently Asked Questions
- What makes the ECCO8 different from a standard column cap?
- The ECCO8 features a legless design, meaning it does not have pre-installed legs like a traditional column cap. Instead, it is intended for field-welded attachment directly to steel columns and beams, making it suitable for end-of-beam applications where leg-style caps cannot be used.
- What type of structural applications is the ECCO8 designed for?
- The ECCO8 is engineered for end-of-beam applications on top of steel members, where a column-to-beam connection is required at the end of a beam rather than at a mid-span or interior position. Its extended seat bearing surface and increased uplift load capacity also make it well-suited for structures subject to earthquake or wind loading conditions.
- What material and finish is the ECCO8 constructed from?
- The ECCO8 is fabricated from heavy-duty 3-gauge steel and features a Simpson Strong-Tie Gray paint finish, providing a durable construction suitable for demanding structural applications.
- Does the ECCO8 meet any recognized structural codes for bolt spacing?
- Yes, the bolt spacing on the ECCO8 meets National Design Specification (NDS) code requirements to help ensure optimal structural performance. The connector also includes integrated diamond holes to allow for convenient temporary fastening during installation.
