The Simpson 10X Beam End Column Cap with Legs Omitted is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections on top of steel members. Built by Simpson from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this legless cap is designed to be attached via field welding directly to steel columns and beams, giving structural professionals a reliable solution wherever a standard legged cap cannot be used. The seat of the cap extends beyond one side of the column, providing added bearing surface area that helps distribute beam loads effectively across the connection point.

Key Features

• Legless configuration designed for field welding - eliminates the constraints of pre-formed leg extensions, allowing direct attachment to steel columns, pipe columns, or other column types without requiring pre-drilled or factory-set leg positions
• Extended seat beyond the column face - increases bearing surface area on one side of the column, helping to distribute beam loads more evenly and strengthen the overall connection
• 3-gauge steel construction - delivers the structural rigidity and load capacity demanded by heavy timber-to-steel connections in challenging structural environments
• Simpson Strong-Tie Gray paint finish - provides a consistent, professional appearance and baseline surface protection suited to structural applications
• Supports uplift resistance for seismic and high-wind loading - makes this connector suitable for structural applications in regions subject to lateral and uplift forces, broadening its use across a range of building codes and conditions
• Compatible with pipe columns and other non-standard column types via field welding - gives engineers and contractors flexibility to adapt the connector to a wider variety of structural column configurations

Why This Product

• Purpose-built for steel-to-timber end-of-beam connections - the legless design directly addresses a specific structural challenge, making it the right fit for applications where standard column caps with legs are not practical or structurally appropriate
• Field-welding flexibility expands application options - because attachment is completed on-site by the designer, this cap can be adapted to pipe columns and other column types, giving project teams greater control over connection details without relying on factory-configured leg placements
• Heavy 3-gauge steel supports demanding load requirements - the robust material gauge is well-suited to the structural loads associated with heavy timber framing, seismic design requirements, and high-wind construction scenarios
• Backed by the Simpson brand - a name widely recognized among structural engineers and contractors for consistent quality and code-compliant connector solutions in wood and steel construction

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.
