The Simpson ECCO68 6X Beam End Column Cap is a heavy-duty structural connector built for end-of-beam column-to-beam connections on top of steel members. Engineered with legs omitted, this 3-gauge steel end cap is designed for field-welded attachment to steel columns and beams, giving fabricators and contractors a weld-ready solution for demanding structural framing applications. The extended bearing seat reaches beyond one side of the column to help distribute beam loads across a wider surface area, supporting robust, reliable connections where enhanced uplift resistance for seismic or wind loading is required.

Key Features

• Legs Omitted Configuration - purpose-built for field-welded attachment to steel columns and beams, eliminating pre-attached legs that would interfere with custom weld connections on steel members.
• 3-Gauge Steel Construction - heavy material gauge delivers the structural rigidity needed for load-bearing column-to-beam connections in demanding framing applications.
• Extended Bearing Seat - the seat projects beyond one side of the column to distribute beam load across a greater bearing surface, improving load transfer at end-of-beam connections.
• 9 1/2 in. Overall Length - the L dimension accommodates beams in the 5 1/4 in. to 5 1/2 in. width range, supporting precise fit for standard 6X beam framing.
• Simpson Strong-Tie Gray Paint Finish - factory-applied coating provides a consistent, professional appearance and baseline protection suited to structural steel environments.
• Versatile Welded Application - compatible with pipe columns and other non-standard column profiles when weld details are specified by the designer, broadening its use across project types.
• United States Origin - produced domestically under Simpson quality standards, supporting consistent material and manufacturing specifications.

Why This Product

• Engineered for Steel-to-Timber End Connections - the ECCO68 is specifically configured for end-of-beam positions on top of steel members, making it the correct choice when a standard interior column cap will not fit the application geometry.
• Weld-Ready Design Saves Fabrication Steps - the legs-omitted format means the cap arrives ready for direct field welding to steel columns and beams, fitting cleanly into steel-framed structural assemblies without modification.
• Supports Seismic and Wind Load Requirements - approved for structural framing applications requiring enhanced uplift resistance, this connector addresses code-driven performance demands in high-load environments.
• Adaptable to Non-Standard Column Profiles - the ECCO68 can be field welded to pipe or other column types as specified by the designer, giving project teams flexibility when standard round or square column hardware is not a match.

Installation Notes

• 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.
• Contact engineered wood manufacturers for connections that are not through the full beam.

Frequently Asked Questions

What makes the ECCO68 different from a standard column cap?

The ECCO68 features a legs-omitted design, which means it is intended for field-welded attachment to steel columns and beams rather than relying on integrated legs for fastening. This makes it especially suitable for end-of-beam applications on top of steel members.

What beam widths are compatible with the ECCO68?

The ECCO68 is compatible with beam widths of 5-1/4 inches and 5-1/2 inches, with a W1 dimension of 5-1/2 inches and a length dimension of 9-1/2 inches.

Does the ECCO68 provide resistance against uplift forces from wind or seismic events?

Yes. The ECCO68 features uplift loads increased to accommodate earthquake or wind
