The Simpson OU610 Ornamental Joist Hanger is a 7-gauge, face-mount connector sized precisely for 6x10 dimensional lumber, engineered to deliver a secure, load-bearing connection between a joist and a header in exposed and architecturally prominent structural assemblies. Finished in a black powder coat, this hanger is equally at home in decorative timber framing, pergola construction, and glulam beam applications where hardware visibility demands both structural reliability and a refined, consistent appearance.

Key Features

• 7-Gauge Steel Construction - Heavy-duty material provides the rigidity and strength needed for demanding structural connections, giving you confidence in long-term performance for timber framing and similar load-bearing assemblies.
• Face-Mount Design - Attaches directly to the face of the header, simplifying installation alignment and keeping the connection tight and secure without complicated hardware.
• Black Powder-Coat Finish - Delivers a clean, decorative appearance that blends seamlessly with surrounding dark hardware, making it the right choice for exposed structural applications where raw steel would detract from the finished look.
• Sized for 6x10 Lumber - Precisely dimensioned to fit standard 6x10 joists with a snug, accurate fit, eliminating guesswork and reducing installation time.
• Glulam Beam Compatibility - Suited for glulam beam connections in addition to standard dimensional lumber applications, broadening its usefulness across a range of engineered timber projects.
• Made in the United States - Domestic production supports consistent quality standards and reliable material sourcing.

Why This Product

• Structure and aesthetics in one hanger - The black powder-coat finish means you do not have to choose between a strong connection and a polished, decorative result - this hanger is built to be seen without compromising structural integrity.
• Purpose-built fit for 6x10 timber - Rather than adapting a general-purpose hanger, you get a connector engineered specifically for 6x10 joists, which translates directly to a more secure, properly seated connection on the job.
• Versatile across ornamental and engineered timber applications - Whether you are framing a pergola, an exposed timber ceiling, or a glulam beam assembly, this hanger covers a meaningful range of decorative structural contexts from a single SKU.
• Heavy-gauge confidence at visible connection points - 7-gauge steel construction means this hanger holds its own structurally even in applications where it is fully exposed to view, so you are not trading away load capacity for looks.
