The Simpson WP11 Welded Top-Flange Joist Hanger from Simpson is built to support 1-3/4 in. x 11-7/8 in. engineered wood joists on purlins or beams in both wood-to-wood and wood-to-steel structural connections. The welded top-flange design accommodates skewed installations up to 84 deg. and sloped conditions up to 45 deg., giving installers the flexibility to handle complex framing layouts without reaching for specialty hardware. An economical nail pattern keeps installed costs low while still delivering maximum download performance, making this hanger a practical choice for engineered lumber framing in residential and commercial construction.

Key Features

• Skewable up to 84 deg. and slopable up to 45 deg. - adapts to angled and compound framing conditions without custom fabrication, reducing jobsite problem-solving time.
• Top flange may be sloped to a maximum of 35 deg. to accommodate a sloped header - lets the hanger conform to pitched header configurations, expanding its usefulness across roof and floor framing scenarios.
• Solid one-piece top flange construction - provides extra stability in panelized roof applications where consistent hanger rigidity is critical to system performance.
• Highly modifiable with alteration options including opened/closed top flange and offset top flange - allows the hanger to be field-adapted or configured for non-standard connection geometries, reducing the need for multiple hanger SKUs on a project.
• 7-gauge steel top flange paired with a 12-gauge stirrup - the heavier top flange delivers structural stiffness at the bearing point while the lighter stirrup keeps overall weight and material cost efficient.
• Simpson Strong-Tie gray paint finish - provides a consistent, recognizable finish and baseline corrosion resistance suitable for protected interior framing applications.
• Low nail count required for maximum downloads - minimizes installation time and fastener cost without compromising rated load performance.

Why This Product

• Unmatched angular flexibility in a single hanger - the ability to skew up to 84 deg. and slope up to 45 deg. means one hanger model handles a wide range of framing challenges, from standard bays to heavily skewed or sloped joist runs.
• Engineered specifically for engineered lumber - sized precisely for 1-3/4 in. x 11-7/8 in. engineered wood members with a 1-13/16 in. seat width, this hanger fits LVL and I-joist framing accurately without shimming or modification.
• Economical installed cost without structural compromise - the minimal nail requirement translates directly into faster installation and lower labor expense, making it a cost-effective solution for large-scale framing where hangers are installed in volume.
• Broad application range across connection types - approved for wood-to-wood and wood-to-steel connections as well as panelized roof systems and sloped header installations, this hanger covers multiple project scenarios with a single, familiar product.
