Product Description
The Simpson WP410 Welded Top-Flange Joist Hanger is built to support joists on purlins or beams in both wood-to-wood and wood-to-steel structural connections. Designed with a solid one-piece top flange for added rigidity and a heavy-gauge steel stirrup for reliable load transfer, this top-flange hanger handles demanding framing conditions including skewed and sloped configurations. Its economical design requires only a small number of nails to achieve maximum download capacity, keeping installation straightforward and installed costs low across a wide range of structural framing applications.
Key Features
- Skew range up to 84 deg. - accommodates severely angled framing layouts without the need for custom fabrication, giving installers flexibility on complex jobs.
- Slope capacity up to 45 deg. - supports steeply pitched roof and floor framing applications where standard hangers fall short.
- Top flange slope up to 35 deg. for sloped headers - allows the flange itself to follow a sloped bearing surface, maintaining full contact and connection integrity.
- Solid one-piece top flange construction - provides extra stability in panelized roof applications where consistent flange rigidity is critical to keeping panels aligned during assembly.
- 7-gauge steel top flange paired with a 12-gauge stirrup - delivers a purposeful balance of heavy-duty bearing strength at the top and lightweight efficiency at the seat, optimized for this member size.
- Alteration options including opened/closed top flange and offset top flange - make this hanger highly modifiable to suit unique site conditions without requiring a fully custom connector.
- Simpson Strong-Tie gray paint finish - provides a consistent, corrosion-resistant coating suited for standard interior and protected structural framing environments.
Why This Product
- Exceptional angular versatility in a single connector - the ability to skew up to 84 deg. and slope up to 45 deg. means one hanger model covers a broad range of framing scenarios, reducing the need to source multiple specialty connectors for a single project.
- Economical installed cost - the low nail count required for maximum download capacity cuts both material and labor time, making the WP410 a practical choice on volume framing projects without sacrificing structural performance.
- Built-in adaptability for real job-site conditions - modification options such as opened or closed top flange and offset top flange configurations allow contractors to fine-tune the connector on site, reducing delays caused by non-standard framing geometry.
- Reliable performance in both wood-to-wood and wood-to-steel applications - the WP410 transitions cleanly between timber-framed and steel-beam support structures, making it a consistent go-to connector for mixed-material construction.
