The Simpson OCC44 Ornamental Column Cap 4x4 Black Powder Coated is a decorative structural connector from Simpson designed to create high-capacity column-to-beam connections in interior architectural applications. With its distinctive notched-edge styling from the Rustic Collection and a refined black powder-coat finish, this 4x4 column cap is built to perform where the hardware stays visible - delivering both structural integrity and a polished, intentional look in residential and commercial interior projects.

Key Features

• Ornamental notched-edge design from the Rustic Collection - purpose-built for exposed-connector installations where the hardware is part of the aesthetic, not hidden behind drywall or trim
• Black powder-coat finish - provides a durable, architectural appearance that holds up to regular interior conditions while complementing timber-frame and rustic-style design schemes
• 3-gauge steel construction - delivers high-capacity load transfer from beam to column, supporting a continuous load path with the strength and certified weld quality the connector demands
• Enhanced uplift resistance - engineered to perform under earthquake and wind loading scenarios, adding an extra layer of confidence for projects in demanding structural environments
• Diamond holes for temporary fastening - simplify alignment during installation, helping ensure accurate positioning before final 5/8 in. machine bolt fastening
• Made in the United States - backed by domestic manufacturing standards consistent with Simpson's quality expectations for structural connectors

Why This Product

• Structural performance with visible appeal - unlike utility connectors meant to be concealed, the OCC44 is specifically designed for exposed use, so you get full load-path integrity without sacrificing the finished look of your interior column-beam assembly
• Purpose-matched sizing for standard 4x4 lumber - with both width dimensions set to 3 5/8 in., this cap fits standard 4x4 columns precisely, reducing the guesswork and ensuring a clean, flush connection right out of the box
• A finish that does double duty - the black powder-coat coating is not just decorative; it shields the steel in interior environments while giving architects and builders a consistent, professional-grade appearance across exposed hardware
• Confidence-backed uplift resistance - for projects in earthquake- or wind-prone regions, the OCC44 is engineered with enhanced uplift resistance, meaning your column cap contributes actively to the structure's ability to handle lateral and vertical loads
