The Simpson HSUL4.75/14 Skewed Left Joist Hanger is a heavy-duty, 45 deg. skewed-left hanger from Simpson designed to provide reliable structural support for large joist members and double I-joists in wood-frame construction. Its heavy U-shaped profile fully encapsulates the top flange of the joist, making it the right choice for framing connections where the geometry requires a left-skewed 45 deg. angle and a standard straight hanger simply will not work.

Key Features

• 45 deg. Skewed Left Geometry - Engineered specifically for left-skewed framing connections, allowing builders to create accurate angular junctions that straight or standard hangers cannot accommodate.
• Heavy U-Shaped Profile - Fully encapsulates the top flange of the supported joist, eliminating the need for web stiffeners during standard installation and simplifying the overall framing process.
• 14-Gauge Construction - Delivers the structural strength required for heavy-duty wood-frame applications, providing confidence in high-load joist connections.
• Zinc Galvanized G90 Coating - Provides durable corrosion resistance suited to demanding construction environments, helping the hanger maintain long-term performance after installation.
• Compatible with Double I-Joists - Sized to support both large solid sawn joist members and double I-joists, giving framing crews flexibility across common heavy-duty applications.
• Domestic Manufacturing - Produced in the United States, supporting consistent quality standards and reliable availability for professional framing projects.

Why This Product

• Solves a Specific Geometric Problem - When a framing layout calls for a 45 deg. left-skewed joist connection, this hanger provides a purpose-built solution rather than a compromise, keeping structural connections clean, accurate, and code-conscious.
• No Web Stiffeners Required - The full top-flange encapsulation design removes an extra installation step that other hanger profiles may require, saving time on the job without sacrificing connection integrity.
• Built for Large and Heavy Members - With interior dimensions suited to large joist members and double I-joists, this hanger is matched to the demanding end of residential and light commercial wood framing rather than light-duty applications.
• Long-Term Corrosion Protection - The G90 zinc galvanized finish means the hanger is built to resist degradation over time, reducing concerns about premature corrosion in the connection once walls, floors, or roofs are enclosed.

Frequently Asked Questions

What size joist is this hanger designed to accommodate?

The HSUL4.75/14 has an interior width (W) of 4-3/4 in. and a height (H) of 13-3/4 in., making it designed to support large joist members or double I-joists in wood construction.

Do I need web stiffeners when installing this hanger?

No. The HSUL4.75/14 features a heavy U-shaped profile that fully encapsulates the top flange of the joist, eliminating the need for web stiffeners during standard installation.

What is the skew direction and angle of this hanger?

This hanger is engineered specifically for a 45-degree skewed-left connection. It is intended for framing applications where a left-skewed angular connection is required and a standard non-skewed hanger cannot be used.

What gauge and finish does the HSUL4.75/14 use, and why does it matter?

The hanger is constructed from 14-gauge steel with a zinc galvanized G90 finish. The heavy 14-gauge material provides superior load-carrying capacity and structural durability, while the G90 galvanized coating delivers enhanced corrosion resistance for long-lasting performance in demanding framing applications.
