The Simpson OU812 Ornamental Joist Hanger 8x12 Black Powder Coated is a 7-gauge, face-mount structural connector designed to join an 8x12 joist to a header with both reliable holding strength and a finished, architectural appearance. Built by Simpson, this hanger is purpose-made for exposed timber framing and decorative beam applications where the hardware itself is part of the visual design - delivering a clean, ornamental look without sacrificing structural performance.

Key Features

• 7-Gauge Steel Construction - Heavy-duty material thickness provides robust load-bearing capacity suited to demanding timber framing connections.
• Black Powder-Coat Finish - A smooth, decorative coating gives the hanger a refined appearance that complements exposed beams and architectural timber work where visible hardware is part of the design intent.
• Face-Mount Design - Attaches directly to the face of the header for a clean, low-profile installation that works well in both residential and commercial ornamental framing.
• Precise 8x12 Fit - Dimensioned specifically for an 8x12 joist profile, ensuring a tight, accurate fit that simplifies installation and supports consistent, secure connections.
• 3/4 in. Anchor Bolt Fastening - Engineered to work with 3/4 in. diameter anchor bolts, providing a high-strength mechanical connection appropriate for heavy timber applications.
