The Simpson Heavy Skewed Left Joist Hanger is a heavy-duty, U-shaped connector engineered to handle angled framing connections where a large joist or double I-joist meets a header or beam at a 45 deg. left offset. Its fully encapsulating profile eliminates the need for web stiffeners in standard installations, saving time and simplifying the framing process. Designed for demanding wood-frame construction applications, this galvanized steel hanger delivers dependable load transfer and corrosion resistance in both interior and exterior structural settings.

Key Features

• 45 deg. Skewed-Left Design - Allows precise angled framing connections at a 45 deg. left offset, eliminating the need for field modifications or custom fabrication when standard square connections are not feasible.
• Heavy U-Shaped Profile - Fully encapsulates the top flange of the joist so no web stiffeners are required for standard installation, reducing hardware costs and streamlining the build process.
• 14-Gauge Steel Construction - Provides the structural rigidity needed to support large joist members and double I-joists in demanding load applications, giving builders confidence in long-term performance.
• G90 Zinc Galvanized Coating - Offers reliable corrosion resistance in a variety of framing environments, helping the hanger maintain its structural integrity over the life of the structure.
• Concealed-Flange Configuration Available - The A2 (acute) flange can be turned in to accommodate end-of-wall installation for solid sawn sizes, giving contractors flexibility on job sites where standard flange orientation is not practical.
• Domestic Manufacturing - Produced in the United States to consistent quality standards, supporting confidence in material sourcing and production oversight.

Why This Product

• Eliminates a Common Installation Headache - Because the heavy U-shaped hanger fully encapsulates the joist's top flange, web stiffeners are not required under standard conditions, cutting down on extra parts and labor during framing.
• Purpose-Built for Angled Framing - The 45 deg. left-skew geometry is engineered specifically for connections that cannot be made with a standard square hanger, making it the correct solution for skewed joist-to-beam connections in wood-frame construction rather than a workaround.
• Handles Heavy Structural Loads - With 14-gauge steel construction and a profile sized to support large joist members and double I-joists, this hanger is suited for applications where undersized connectors would be a liability.
• Flexible Configuration for Tight Installations - The option to orient the acute flange inward for end-of-wall installations means contractors working with solid sawn lumber are not forced into a one-size-fits-all solution when space is limited.

Frequently Asked Questions

What is the difference between the HSUR and the HSUL?

The HSUR and HSUL hangers are identical in design and dimensions except that the HSUR is skewed 45 degrees to the right and the HSUL is skewed 45 degrees to the left. The HSUL5.12/9 is the left-skewed version.

Are web stiffeners required when installing the HSUL5.12/9?

No. Because this heavy U-shaped hanger encapsulates the top flange of the joist, no web stiffeners are required for standard installation.

What type of joist members does the HSUL5.12/9 support?

The HSUL5.12/9 is designed to support large joist members or double I-joists in wood construction applications.

What coating does the HSUL5.12/9 have, and why does it matter?

The HSUL5.12/9 features a Zinc Galvanized, G90 coating, which provides corrosion resistance
