Product Description
The Simpson WP48 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. Engineered by Simpson Strong-Tie for exceptional flexibility, it can be skewed up to 84 deg. and/or sloped to a maximum of 45 deg., adapting to a wide range of framing angles and job-site conditions. Its economical design requires only a small number of nails to achieve maximum download capacity, keeping installed costs low without compromising structural performance. The solid one-piece top flange adds stability in panelized roof applications, while multiple alteration options make this hanger a highly adaptable solution for complex framing layouts.
Key Features
- Skewable up to 84 deg. and slopeable up to 45 deg. - accommodates a wide variety of framing angles so the hanger fits the structure rather than forcing adjustments to your layout.
- Solid one-piece top flange - delivers extra stability in panelized roof applications, reducing movement and helping maintain consistent alignment during installation.
- Top flange may be sloped up to 35 deg. - allows the hanger to match a sloped header directly, eliminating the need for custom workarounds in pitched framing assemblies.
- Highly modifiable with alteration options including opened/closed top flange and offset top flange - gives installers the ability to tailor the hanger to specific connection requirements on the job site.
- Dual-gauge construction - 7-gauge top flange and 12-gauge stirrup - pairs a heavy-duty flange for load transfer with a lighter stirrup for practical handling, balancing strength and ease of installation.
- Low nail count for maximum download capacity - reduces installation time and fastener costs while still meeting full load requirements.
- Simpson Strong-Tie gray paint finish - provides a consistent, clean appearance and a baseline level of surface protection across the connector.
Why This Product
- Unmatched angular flexibility for complex framing - the ability to skew up to 84 deg. and slope up to 45 deg. in a single connector means fewer compromises and fewer specialty parts needed across a wide range of structural configurations.
- Built for both wood and steel supporting members - approved for wood-to-wood and wood-to-steel applications, this joist hanger works across different structural systems without requiring a different product for each scenario.
- Economical to install without sacrificing capacity - the low nail count required for full download ratings translates directly to faster installations and lower labor costs on production framing and panelized roof jobs.
- Highly configurable for non-standard conditions - with alteration options for open or closed top flanges, offset top flange, and top flange slope up to 35 deg., this connector adapts to demanding connections that standard off-the-shelf hangers cannot easily address.
