The Simpson OU810 Ornamental Joist Hanger is a 7-gauge, face-mount connector sized specifically for 8x10 lumber, built to deliver dependable structural performance in applications where hardware appearance is part of the design. The black powder-coat finish gives exposed timber connections a refined, intentional look that suits pergolas, pavilions, heavy timber interiors, and other ornamental framing projects where standard galvanized hardware would undercut the aesthetic. Every OU810 is fabricated by Simpson with the precision and consistency the brand is known for in structural connectors.

Key Features

• Face-Mount Connection - attaches directly to the face of a structural header, creating a clean, secure joist-to-header joint that keeps the connection tight and properly aligned without the need for additional blocking.
• 7-Gauge Steel Construction - heavy-gauge steel provides the load-carrying capacity needed for demanding ornamental timber framing, giving builders confidence in long-term structural reliability even in large-span outdoor structures.
• Black Powder-Coat Finish - the durable powder-coat surface delivers a consistent, attractive appearance that integrates naturally into exposed timber designs, eliminating the visual mismatch common with utility-grade hardware.
• Precision Sizing for 8x10 Lumber - machined to fit standard 8x10 stock, the hanger seats snugly without shimming or field modification, saving installation time and reducing the risk of misalignment.
• 3/4 in. Anchor Bolt Installation - designed around 3/4 in. diameter anchor bolts, the fastener pattern supports a secure, code-compliant connection between joist and header in both indoor and outdoor ornamental applications.
• Glulam Beam Compatibility - in addition to sawn lumber, the OU810 is approved for glulam beam connections, broadening its use across a range of engineered timber assemblies.

Why This Product

• Form and function in one connector - the black powder-coat finish means buyers do not have to choose between structural integrity and visual appeal; this hanger is purpose-built for projects where both matter equally, from interior heavy timber ceilings to open-air pavilion structures.
• Trusted Simpson engineering - the OU810 comes from Simpson, a brand widely recognized for precision-manufactured structural connectors, so contractors and designers can specify it with confidence across residential and commercial ornamental timber applications.
• Broad application range - approved for sawn lumber and glulam beam connections alike, and well suited to pergolas, pavilions, and exposed interior framing, the OU810 covers a wider variety of ornamental timber projects than a single-use specialty hanger typically would.
• Straightforward installation - the face-mount design and defined 3/4 in. anchor bolt requirement keep the installation process predictable and repeatable, reducing on-site decision-making and helping crews work efficiently on multi-connection timber frames.

Frequently Asked Questions

What joist size is the OU810 designed to fit?

The OU810 is precisely sized to fit standard 8x10 lumber, providing a reliable, snug fit for that specific joist dimension.

What type of fasteners are required to install the OU810?

The OU810 installs using 3/4 in. diameter anchor bolts, which provide a secure, code-compliant connection between the joist and the header.

Is the OU810 suitable for exposed or visible framing applications?

Yes. The OU810 features a black powder-coat finish specifically intended to enhance visual appeal in exposed structural settings, making it well suited for ornamental timber framing where appearance is as important as structural performance.

How is the OU810 mounted, and what gauge steel is it made from?

The OU810 uses a face-mount design, connecting the joist directly to the face of a header for a clean, secure structural connection. It is constructed from 7-gauge steel, which provides superior strength and durability for demanding ornamental framing applications.
