The Simpson ECC78PC 6-3/4 in Beam 8X Post Black End Column Cap is a heavy-duty structural connector from Simpson built for end-of-beam column-to-beam connections in wood construction. Sized specifically for a 6-3/4" beam and an 8X post, this connector features an extended seat that provides additional bearing surface beyond one side of the column, helping distribute beam loads effectively at end-of-run positions. The black powder-coat finish gives it a clean, finished appearance suited for exposed structural applications, while its robust steel construction supports reliable performance in demanding wood-framed assemblies.

Key Features

• End-of-Beam Seat Design - The extended seat geometry reaches beyond one side of the column, providing additional bearing area that helps transfer beam loads effectively in end-of-beam configurations.
• Certified Welds - Professionally certified welds deliver confidence in strength and load-carrying capacity, supporting structural reliability throughout the connection.
• Increased Uplift Load Values - Uplift resistance is enhanced to meet the demands of seismic zones and high-wind regions, making this cap a practical choice where code-required uplift performance matters.
• Black Powder-Coat Finish - The durable black finish protects the steel and provides a consistent, polished look for post-and-beam assemblies where the hardware will remain visible.
• Heavy-Gauge Steel Construction - Built from 3 gauge steel, this end column cap is engineered to handle the structural loads typical of 8X post applications without compromise.
• NDS-Compliant Bolt Pattern - Designed to accommodate NDS-compliant bolt spacing using 3/4" machine bolts, supporting code-conforming installations in permitted projects.
• American-Made Quality - Produced in the United States, this connector reflects the manufacturing standards that structural professionals rely on for consistent, traceable hardware.

Why This Product

• Purpose-Built for End-of-Beam Connections - Unlike standard column caps, the ECC78PC is specifically engineered for end-of-beam positions, where its extended seat geometry provides the bearing area needed to handle real-world structural loads at terminal beam locations.
• Seismic and High-Wind Ready - With increased uplift load values built into its design, this cap is well suited for post-and-beam assemblies in regions where wind or seismic forces demand more from structural connectors.
• Finished Look Without Extra Work - The black powder-coat finish means exposed hardware in architectural or outdoor post-and-beam applications looks intentional and complete, without requiring additional finishing steps on-site.
• Configurable for Project-Specific Needs - Straps may be rotated 90 deg. and optional dimensions can be specified for non-standard lumber, giving builders flexibility when working with varied framing conditions.

Frequently Asked Questions

What beam and post sizes is the ECC78PC designed to fit?

The ECC78PC is designed specifically for a 6-3/4" beam and an 8X post, making it important to confirm your lumber dimensions match before installation.

What makes this an "end" column cap rather than a standard column cap?

The ECC78PC is engineered for end-of-beam applications. Its seat extends beyond one side of the column, increasing the bearing surface area for effective load distribution in situations where the beam terminates at the column rather than passing over it.

Is the ECC78PC suitable for use in high-wind or seismic zones?

Yes. The ECC78PC features increased uplift load values specifically intended to meet the demands of earthquake and wind loading conditions, making it appropriate for use in structurally demanding applications where these forces are a concern.

What material and finish does the ECC78PC use, and is it appropriate for exposed applications?

The ECC78PC is constructed from heavy-duty 3-gauge steel and features a durable black powder-coat finish. This finish provides a clean, finished appearance that is suitable for exposed applications where the connector will remain visible.
