The Simpson HSUL46Z ZMAX Skewed Left Joist Hanger is a heavy-duty, U-shaped connector from Simpson engineered to support 4x6 large joist members and double I-joists in wood-framed construction at a 45 deg. left skew angle. Built to 14-gauge steel with a ZMAX coating for enhanced corrosion resistance, this hanger delivers reliable structural performance in angled framing applications where a precise left-hand skewed connection is required.

Key Features

• 45 deg. Skewed Left Orientation - Purpose-built for left-hand angled framing connections, ensuring accurate alignment and structural integrity where standard square hangers cannot be used.
• Top-Flange Encapsulation Design - The heavy U-shaped profile encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installation and reducing labor and material costs on the job site.
• 14-Gauge Steel Construction - Provides the load-carrying capacity and rigidity needed to support large solid sawn lumber and double I-joist members in demanding wood construction applications.
• ZMAX Coating - Offers enhanced corrosion resistance compared to standard coatings, making this hanger well suited for applications where long-term durability and coating performance are a priority.
• Supports Double I-Joists - Accommodates both solid sawn 4x6 lumber and double I-joist configurations, giving builders flexibility across a range of framing assemblies without requiring a different connector.

Why This Product

• Solves a Specific Framing Challenge - A 45 deg. skewed left connection is a common requirement in complex roof and floor framing layouts, and this hanger is engineered specifically to handle that angle accurately with a heavy-duty build to match.
• Simplifies Installation - Because the top-flange encapsulation design eliminates the web stiffener requirement for standard installation, contractors can complete angled joist connections faster and with fewer components.
• Built for Large Lumber Sizes - Designed to carry 4x6 and double I-joist members, this connector addresses the heavier end of residential and light commercial framing needs where undersized hangers are not appropriate.
• Domestic Quality from a Trusted Brand - Produced by Simpson and made in the United States, this hanger is consistent with the material and dimensional standards that structural framing applications demand.

Frequently Asked Questions

What size joist is the HSUL46Z designed to support?

The HSUL46Z is engineered to support 4 x 6 joist members, including solid sawn lumber and double I-joist configurations. Its heavy U-shaped design accommodates large joist members in wood construction.

Do I need web stiffeners when installing this hanger?

No. The HSUL46Z features a top-flange encapsulation design, meaning the heavy U-shaped hanger encapsulates the top flange of the joist. This eliminates the need for web stiffeners in standard installation, streamlining the building process.

What does the ZMAX coating provide, and is it suitable for treated lumber?

The ZMAX coating provides an elevated level of corrosion resistance compared to standard G90 galvanizing. This makes the HSUL46Z suitable for use with treated lumber environments where standard coatings may not offer adequate protection.

What are the key dimensions and gauge of the HSUL46Z?

The HSUL46Z is constructed from 14-gauge steel and has the following dimensions: Width (W) of 3 9/16 in., Height (H) of 4 3/4 in., and Bearing (B) of 2 7/16 in. It is designed for 45-degree left-skewed framing applications.
