The Simpson ECC66PC Black End Column Cap is a heavy-duty structural connector from Simpson engineered for end-of-beam column-to-beam connections in wood construction. Built for use with 6x beams and 6x posts, this end column cap features a seat that extends beyond one side of the column, providing additional bearing surface to effectively distribute loads from the beam and deliver robust support at the connection point. Its durable black powder-coat finish and certified welds make it equally at home in exposed architectural timber framing and demanding structural environments subject to seismic or high-wind loading.

Key Features

• Certified Welds - engineered weld quality gives builders and inspectors confidence in the connector's strength and load-carrying capacity at every critical joint.
• 7-Gauge Steel Construction - heavy-gauge steel provides the structural rigidity needed for post-and-beam framing applications where load demands are high.
• Extended Seat Design - the seat projects beyond one side of the column, increasing the bearing surface area so beam loads are distributed more effectively at the connection point.
• Black Powder-Coat Finish - delivers a clean, finished appearance that suits exposed architectural timber framing while also protecting the steel against wear.
• Seismic and High-Wind Resistance - enhanced uplift resistance makes this connector a dependable choice for structural connections in regions with demanding wind or seismic requirements.
• NDS-Compliant Bolt Spacing - designed to meet National Design Specification bolt spacing requirements, supporting code-conforming installations without extra field modification.
• Configurable Strap Orientation - straps may be rotated 90 deg., giving framers flexibility to adapt the connector to varying site conditions and framing layouts.

Why This Product

• Purpose-Built for End-of-Beam Applications - unlike standard column caps, the ECC66PC is specifically engineered for end-of-beam positions where a seat extension is needed to properly bear and transfer beam loads, making it the right tool for this connection type rather than a workaround.
• Finish That Works in Finished Spaces - the black powder-coat gives the connector a refined look that holds up in exposed timber framing, so structural hardware does not become an eyesore in architectural or decorative post-and-beam assemblies.
• Versatility Through Adjustable Configuration - the ability to rotate straps 90 deg. and to accommodate special or rough-cut lumber sizes with an optional W2 dimension means one connector can adapt to a wider range of framing situations without requiring a completely different product.
• Domestic Manufacturing - produced in the United States under Simpson quality standards, this connector is made to consistent tolerances that support predictable performance in both residential and commercial structural framing.

Frequently Asked Questions

What beam and post sizes is the ECC66PC designed to work with?

The ECC66PC is designed for use with 6x beams and 6x posts, making it suitable for heavy-duty wood construction applications where those lumber dimensions are specified.

What makes the ECC66PC suitable for seismic or high-wind construction environments?

The ECC66PC features certified welds and enhanced uplift load values specifically engineered to meet the demands of earthquake or wind loading scenarios, making it appropriate for use in structurally demanding environments subject to seismic or high-wind conditions.

What is the purpose of the extended bearing seat on the ECC66PC?

The column cap seat extends beyond one side of the column to increase the bearing surface area at the connection point. This design helps distribute loads from the beam more effectively, providing robust support in end-of-beam applications.

What material and finish does the ECC66PC feature?

The ECC66PC is fabricated from 7-gauge steel and finished with a durable black powder-coat. This finish provides a clean, polished appearance well-suited for exposed architectural applications while contributing to the connector's overall durability.
