Product Description
The Simpson WP66 Welded Top-Flange Joist Hanger is engineered to support joists on purlins or beams in both wood-to-wood and wood-to-steel framing applications. Built with a heavy-duty 7-gauge steel top flange and a solid one-piece construction, this hanger delivers the structural reliability and installation flexibility that demanding framing projects require. Its ability to be skewed up to 84 deg. and/or sloped to a maximum of 45 deg. makes it a highly adaptable connector for a wide range of roof and floor framing conditions, while its economical design keeps installed costs low by requiring only a small number of nails for maximum download capacity.
Key Features
- Skews up to 84 deg. and slopes to a maximum of 45 deg. - accommodates complex framing angles without the need for custom fabrication, saving time on difficult connections.
- Top flange may be sloped to a maximum of 35 deg. to accommodate a sloped header - allows a single hanger model to work across sloped-header conditions, reducing the need for specialized hardware.
- Solid one-piece top flange - provides extra stability in panelized roof applications, keeping framing assemblies aligned and secure during installation.
- Highly modifiable with alteration options including opened/closed top flange and offset top flange - gives contractors the ability to adapt the hanger to job-site conditions without sourcing a separate product.
- Top flange made from 7-gauge steel; stirrup made from 12-gauge steel - the heavier-gauge top flange handles the load path where strength matters most, while the lighter stirrup keeps overall weight and material cost in check.
- Simpson Strong-Tie gray paint finish - provides a consistent, clean appearance and a baseline level of corrosion resistance for interior and protected structural applications.
- Wood-to-wood and wood-to-steel compatibility - eliminates the need to stock separate hangers for different beam or purlin materials on mixed-material framing projects.
Why This Product
- Exceptional versatility across framing configurations - the combination of up to 84 deg. of skew and 45 deg. of slope in a single welded top-flange hanger means this connector handles the widest range of angled joist connections, from straightforward purlin framing to complex roof geometries.
- Low installed cost without sacrificing load capacity - the WP66 achieves maximum download performance with a minimal nail count, reducing both labor time and fastener costs on every connection.
- One hanger, multiple applications - suitable for wood-to-wood framing, wood-to-steel beam connections, panelized roof assemblies, and sloped-header applications, this hanger reduces the number of SKUs a contractor needs to carry on the job site.
- Modifiable design built for field conditions - with options for an opened or closed top flange and an offset top flange configuration, the WP66 can be adjusted to fit real-world framing conditions rather than requiring the framing to fit the hardware.
