The Simpson OCC66 Ornamental Column Cap 6x6 Black Powder Coated is a decorative structural connector from Simpson engineered to create high-capacity interior column-to-beam connections in timber frame and post-and-beam construction. Part of the Rustic Collection, this 6 x 6 column cap features distinctive notched edges that make it a natural fit for exposed-connector applications where a refined, architectural look is just as important as structural performance. The black powder-coat finish delivers a polished appearance that complements interior timber installations, while the connector's design supports a continuous, reliable load path from beam to column - including resistance to demanding uplift forces from wind or seismic loading.

Key Features

• Black powder-coat finish - provides a clean, refined appearance that suits exposed-connector installations where aesthetics and structural function must work together
• Decorative notched-edge profile - part of Simpson's Rustic Collection aesthetic, making this cap an attractive choice wherever architectural character is required alongside engineered performance
• Increased uplift load capacity - designed to handle demanding lateral and vertical forces, making it appropriate for projects in earthquake- or wind-prone environments
• Diamond holes for temporary fastening - simplify positioning during installation, allowing the connector to be held securely in place before final bolting for a more accurate, efficient installation process
• Certified welds - give builders and inspectors confidence in the connector's strength and load ratings throughout the life of the structure
• Designed for standard 6 x 6 dimensional lumber - fits columns with both W1 and W2 dimensions of 5-1/2 in., ensuring compatibility with common post-and-beam framing members without modification
• Made in the United States - reflects Simpson's commitment to domestic manufacturing quality and consistency

Why This Product

• Structural strength meets architectural appeal - unlike purely utilitarian connectors, this ornamental column cap is engineered for interior applications where the hardware is visible, delivering a Rustic Collection aesthetic without sacrificing load capacity or uplift resistance
• Purpose-built for demanding load conditions - the OCC66's increased uplift capacity makes it a dependable choice for timber frame and post-and-beam projects where wind or seismic forces are a design consideration, going beyond basic gravity-load connections
• Streamlined installation with diamond fastening holes - the built-in temporary fastening feature reduces the guesswork of positioning a heavy connector on a loaded column, helping crews work more accurately and efficiently before final bolting
• A finished, coordinated look right out of the box - the black powder-coat finish is applied at the factory, so the connector arrives ready to install in exposed interior settings without any additional finishing work required on site
