Product Description
The Simpson WP412 Welded Top-Flange Joist Hanger is built to support 4x12 joists on purlins or beams in both wood-to-wood and wood-to-steel structural framing applications. Constructed with a 7-gauge top flange and 12-gauge stirrup, this hanger delivers a strong, dependable connection while keeping installed costs low - requiring only a small number of nails to achieve maximum download capacity. Its capacity to be skewed up to 84 deg. and/or sloped to a maximum of 45 deg. makes it a highly adaptable solution for complex roof and floor framing configurations where standard hangers fall short.
Key Features
- Skews up to 84 deg. and slopes up to 45 deg. - accommodates angled and compound framing conditions without requiring custom fabrication, saving time on complex structural layouts.
- Solid one-piece top flange design - provides extra stability in panelized roof applications, reducing movement and maintaining alignment during installation.
- Top flange can slope up to 35 deg. - allows the hanger to connect directly to a sloped header, eliminating the need for additional blocking or shimming in pitched framing scenarios.
- Highly modifiable with alteration options including opened/closed top flange and offset top flange - gives installers the flexibility to adapt the hanger to site-specific conditions without sourcing a separate product.
- Dual-material compatibility for wood-to-wood and wood-to-steel connections - makes this a single versatile hanger suitable across different structural systems, reducing the number of SKUs a contractor needs on the job site.
- 7-gauge top flange paired with a 12-gauge stirrup - balances structural strength at the bearing point with the appropriate flexibility in the stirrup, optimizing load transfer for 4x12 lumber.
- Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and basic surface protection suited to interior structural framing environments.
Why This Product
- Exceptional angular range for demanding framing jobs - the ability to skew up to 84 deg. and slope to 45 deg. means this welded top-flange hanger handles the most challenging roof and floor framing geometries that standard joist hangers cannot address, reducing the need for field modifications.
- Economical installed cost without sacrificing performance - the low nail count required for maximum download capacity means faster installation and reduced labor time, making this hanger a cost-effective choice for both small projects and large-scale panelized roof construction.
- One hanger, two structural systems - verified compatibility with both wood-to-wood and wood-to-steel applications means contractors working across mixed-material framing conditions can rely on a single hanger solution rather than stocking multiple product types.
- Built-in adaptability through modifiable top-flange options - the availability of opened/closed and offset top-flange configurations means the WP412 can be adjusted to meet site conditions, making it a practical choice for projects where framing tolerances or header configurations vary.
