The Simpson OU410 Ornamental Joist Hanger for 4x10 is a face-mount connector from Simpson's decorative hardware line, built to connect a 4x10 joist to a header in exposed wood applications where structural integrity and finished appearance must both be met. Part of the Rustic Collection, this 7-gauge steel hanger arrives pre-finished with a black powder-coat, delivering a load-rated, pre-engineered connection that outperforms custom-fabricated alternatives in both consistency and verified performance.

Key Features

• From the Rustic Collection - purpose-built for ornamental, exposed-wood framing where the connector itself is part of the visual design
• Nominal joist size: 4x10 - sized precisely for standard 4x10 lumber, ensuring a proper, secure fit without field modification
• Seat width: 3-9/16 in. - matches the actual bearing surface of a 4x10 member for stable, even load transfer
• 7-gauge steel construction - heavy-gauge material provides the structural robustness expected for exposed structural connections in residential and light commercial builds
• Black powder-coat finish - delivers a refined, decorative look that complements exposed timber framing while offering surface protection
• Face-mount design - simplifies installation by attaching directly to the header face, keeping the connection point accessible and visible as a design element

Why This Product

• Tested and load-rated for confidence - as a pre-engineered Simpson product, the OU410 is verified to perform to design loads, giving builders and designers a reliable alternative to custom-fabricated connectors that lack documented performance data
• Structural performance meets ornamental design - unlike standard utility hangers hidden inside wall cavities, this connector is engineered to be seen, making it the right choice for open-beam ceilings, exposed deck framing, and timber-frame accent work
• Pre-finished and ready to install - the black powder-coat finish is applied before the product ships, eliminating the need for field painting or finishing and keeping the exposed connector looking intentional and clean
• Made in the United States - manufactured domestically to Simpson's engineering standards, supporting quality consistency across the Rustic Collection connector line
