The Simpson 4 x 14 Concealed Flange Joist Hanger Skewed Left HSULC414 is a heavy-duty connector engineered specifically for 45 deg.-skewed left joist-to-header connections in wood-frame construction. Designed to support 4x14 lumber members, this hanger features a concealed header flange that keeps visible framing lines clean and refined - making it equally suited to exposed-condition applications where appearance matters as much as structural integrity. Its U-shaped seat encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installations and simplifying the overall framing process.

Key Features

• 45 deg.-Skewed Left Configuration - Precisely engineered for left-skewed joist-to-header connections, with a working range of 40 deg. to 50 deg. that accommodates real-world framing tolerances without field modification.
• Concealed Header Flange - Hides the flange behind the header for cleaner visible lines in exposed framing conditions, removing the need to cover or trim hardware after installation.
• 4x14 Member Support - Purpose-built to carry 4x14 lumber, ensuring a secure and properly sized fit without improvised shimming or adapting a hanger meant for a different member size.
• No Web Stiffeners Required - The joist top-flange encapsulation design eliminates web stiffener requirements in standard applications, reducing material needs and saving installation time.
• Square or Bevel Cut Compatibility - Works with both square-cut and bevel-cut joist ends, giving framers flexibility in how they prepare lumber without compromising the connection.
• Turned-In Acute Flange - The A2 flange turns in at the acute angle, making this hanger well suited to end-of-wall installations where standard hangers cannot reach or seat correctly.
• 14-Gauge Zinc Galvanized G90 Steel - The G90 galvanized coating provides corrosion resistance appropriate for typical wood-frame construction environments, supporting long-term connection reliability.

Why This Product

• Built for a specific geometry, not adapted to it - Rather than a field-modified general-purpose hanger, this connector is purpose-designed for 45 deg.-skewed left framing, which means the fit, load path, and flange positioning are all optimized for that exact application from the start.
• Cleaner results in exposed framing - The concealed flange design is a direct advantage on any project where structural connections remain visible after construction, eliminating the hardware-heavy look that standard face-mount hangers leave behind.
• Fewer materials, faster installation - With no web stiffeners needed and compatibility with both square and bevel cut lumber, this hanger reduces the number of extra components and prep steps involved in completing a skewed joist connection.
• Flexibility within a fixed angle - The 40 deg. to 50 deg. accommodation range means framers can work within realistic construction tolerances at a 45 deg.-skewed connection without needing a separate hanger for minor angular variation.

Frequently Asked Questions

What joist size is the HSULC414 designed to support?

The HSULC414 is specifically engineered to support 4x14 lumber members in wood-frame construction.

What angle does the HSULC414 accommodate, and can it be field-modified to fit other skew angles?

The HSULC414 is designed for a 45 deg.-skewed left configuration and cannot be modified. However, it will accommodate a joist skewed anywhere in the range of 40 deg.-50 deg., providing some flexibility around the nominal 45 deg. angle.

Are web stiffeners required when installing the HSULC414?

No, web stiffeners are not required for standard installation. The hanger encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard applications.

Can the joist end be square-cut, or does it need to be bevel-cut to work with this hanger?

The HSULC414 is compatible with both square and bevel cut joist ends, offering flexibility during installation without requiring a specific cut type.
