Simpson Strong-Tie ECCO10 10X Beam End Column Cap (Legs Omitted) is 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 field-welded attachment to steel columns and beams, making it a versatile solution for structural connections where a legless configuration is required. The seat of the cap extends beyond one side of the column to provide additional bearing surface area, effectively distributing beam loads and reinforcing the integrity of the connection. Constructed from heavy-duty 3-gauge steel with a Simpson Strong-Tie Gray paint finish, the ECCO10 is built to perform in demanding structural environments.

Options

• Contact us for Configurable Options and Special orders
• For special, custom, or rough-cut lumber sizes, provide dimensions.
• ECCO may be ordered for field welding to pipe or other columns. Weld by designer.

Installation

• Use all specified fasteners.
• Bolt holes shall be a minimum of 1/32 in. to a maximum of 1/16 in. 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.

Frequently Asked Questions

What does "legs omitted" mean on the ECCO10 column cap?

The ECCO10 is designed without legs, meaning it does not have the standard leg extensions found on other column cap models. This legless configuration allows the cap to be attached via field welding directly to steel columns and beams, making it ideal for steel-to-timber connection applications.

What gauge steel is used in the construction of the ECCO10?

The ECCO10 is constructed from 3-gauge steel, providing heavy-duty strength suitable for demanding structural column-beam connection applications.

What are the bolt hole tolerances required for proper installation of the ECCO10?

Bolt holes must be a minimum of 1/32 in. to a maximum of 1/16 in. larger than the bolt diameter, per 2018 NDS section 12.1.3.2. Holes should be drilled from one side all the way through the beam to maintain proper hole tolerances.

Is the ECCO10 suitable for use in high-wind or seismic applications?

Yes. The ECCO10 features increased uplift load capacity specifically designed to accommodate earthquake and wind loading conditions, making it appropriate for use in seismic and high-wind structural applications.
