The Simpson HSUL5.12/16 Skewed Left Joist Hanger is a heavy-duty, U-shaped connector engineered for 45 deg. left-skewed framing applications in wood construction. Built by Simpson to handle large joist members and double I-joists, this 14-gauge galvanized hanger delivers a reliable, structurally sound connection wherever an angled left-hand joist placement is required - making it the go-to choice for residential and commercial wood-frame projects that demand precision at non-standard angles.

Key Features

• 45 deg. Skewed Left Orientation - Purpose-built for left-hand angled framing, this hanger accommodates joist placement where standard straight connectors simply cannot perform, keeping your framing square and structurally sound.
• Heavy U-Shaped Profile - Fully encapsulates the top flange of the supported joist member, eliminating the need for web stiffeners in standard installations and saving time on the job site.
• 14-Gauge Construction - The heavy gauge steel provides the load capacity needed to support large joist members and double I-joists, giving builders confidence in high-demand structural connections.
• G90 Zinc Galvanized Coating - Corrosion-resistant finish helps protect the connector in typical wood-frame construction environments, supporting long-term connection integrity.
• End-of-Wall Installation Option - Available with the acute flange turned in for end-of-wall placement on solid sawn sizes, adding versatility for situations where standard flange positioning is not practical.
• Domestic Manufacturing - Produced in the United States to consistent quality standards, supporting reliable dimensional accuracy across installations.

Why This Product

• Engineered for a Specific Job - Not every framing connection is straight. The HSUL5.12/16 is purpose-designed for 45 deg. left-skewed joist placement, meaning you get a connector that fits the application correctly rather than a workaround solution.
• Handles Large and Complex Joist Members - Approved for supporting large joist members and double I-joists, this hanger covers demanding structural scenarios that lighter-duty connectors are not rated to handle.
• Simplified Installation - The U-shaped design encapsulates the joist's top flange without requiring web stiffeners in standard use, reducing hardware and labor in the field.
• Flexible Configuration for Tight Spaces - The option to turn the acute flange in for end-of-wall installations on solid sawn sizes means this connector adapts to constrained framing conditions without requiring a separate specialty product.

Frequently Asked Questions

What type of framing application is the HSUL5.12/16 designed for?

The HSUL5.12/16 is purpose-built for left-hand 45-degree skewed framing applications. It provides a structurally sound connection where joists must be placed at a 45-degree angle to the left, making it the correct choice when standard straight hangers cannot accommodate the required skew angle.

Does this joist hanger require web stiffeners during installation?

No. The HSUL5.12/16 features a heavy U-shaped profile that fully encapsulates the top flange of the joist, which eliminates the need for web stiffeners in standard installations. This simplifies the installation process and reduces the need for additional materials.

What gauge steel is used, and what corrosion protection does this hanger have?

This hanger is constructed from 14-gauge steel and features a G90 zinc galvanized coating. The G90 finish provides corrosion resistance suited for treated lumber and protected wood construction environments.

Is there a similar hanger available for end-of-wall installations?

Yes. For end-of-wall installations in solid sawn sizes where a concealed flange is needed, Simpson Strong-Tie offers the HSURC or HSULC series as compatible concealed flange variants of this hanger.
