The Simpson End Column Cap for 7 in. Beam Legs Omitted ECCO7 1/8 is a heavy-duty structural connector from Simpson engineered for end-of-beam column-to-beam connections on top of steel members. Its legless design allows for field-welded attachment directly to steel columns and beams, making it a practical choice for structural steel applications where a clean, high-strength connection is required at the end of a 7 in. beam. The seat extends the bearing surface beyond one side of the column to effectively distribute load and reinforce connection integrity, while the heavy-gauge steel construction delivers long-term reliability in demanding conditions - including applications subject to elevated uplift forces from earthquake or wind events.

Key Features

• End-of-beam, legless column cap design - eliminates pre-attached legs so the connector can be field-welded directly to steel columns, pipe columns, or other column configurations, giving installers precise control over placement and fit.
• Extended seat bearing surface - the seat projects beyond one side of the column to spread load more broadly across the connection, reducing stress concentrations and reinforcing structural performance at the beam end.
• 3-gauge steel construction - heavy material thickness provides the load capacity and rigidity needed for structural steel applications without adding unnecessary bulk to the connection assembly.
• Simpson Strong-Tie Gray paint finish - factory-applied coating helps protect the connector during storage and installation in typical structural environments.
• Approved for seismic and high-wind applications - rated for connections subject to increased uplift loads from earthquake or wind forces, making it suitable for projects with demanding code requirements.
• Compatible with pipe and alternative column profiles - can be ordered and field-welded to pipe or other non-standard column shapes, expanding its usefulness beyond conventional square or rectangular steel columns.
• Made in the United States - domestic production supports consistent quality standards and traceability for projects where origin matters.

Why This Product

• Purpose-built for end-of-beam steel connections - unlike general-purpose column caps, this connector is specifically designed for end-of-beam positioning on top of steel members, so it fits the application without requiring field modification or workarounds.
• Field-weld flexibility for complex steel projects - the legless configuration means the designer controls the weld, enabling custom attachment to steel columns, pipe, or other profiles that standard leg-based connectors cannot accommodate.
• Engineered load distribution where it matters most - the extended seat bearing surface addresses one of the most common weak points in end-of-beam connections by spreading the transferred load, which is especially valuable in seismic zones and high-wind regions.
• From a trusted structural connector brand - Simpson has a long-standing reputation in engineered structural hardware, giving builders, engineers, and inspectors a familiar, widely recognized product at the connection point.
