The Simpson HSULC414 is a heavy-duty, concealed flange joist hanger engineered for 45 deg.-skewed left installations in wood-frame construction. Designed to support 4x14 members, this U-shaped hanger features a concealed header flange that delivers cleaner, more refined visible lines in exposed conditions - making it an ideal choice where aesthetics matter as much as structural performance. Built to exacting standards and manufactured in the United States, the HSULC414 offers reliable load transfer and simplified installation without the need for web stiffeners in standard applications.

Key Features

• 45 deg.-Skewed Left Configuration: Specifically designed to skew left at 45 deg., providing precise angular support for joist-to-header connections where geometry demands it
• Concealed Header Flanges: The concealed flange design provides cleaner visible lines in exposed conditions, combining structural integrity with a finished appearance
• A2 (Acute) Flange Turned In: The acute flange is turned in to accommodate end-of-wall installation, expanding placement versatility
• No Web Stiffeners Required: Encapsulates the top flange of the joist, so no web stiffeners are required for standard installation
• Obround Nail Holes on Acute Side: Features obround nail holes on the acute side, allowing nails to be easily installed parallel to the joist
• Flexible Skew Accommodation: These hangers cannot be modified but will accommodate a 40 deg.- to 50 deg.-skewed joist
• Square or Bevel Cut Compatibility: The joist end may be square cut or bevel cut for installation flexibility
• G90 Zinc Galvanized Coating: Finished with a G90 zinc galvanized coating for corrosion resistance in wood construction environments

Installation

Fasteners are required for proper installation. Use #9 x 2-1/2" Strong-Drive SD Connector screws OR 0.162" x 3-1/2" Nails. Fill all round and obround nail holes with specified fasteners to achieve table loads. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity. The joist end may be square cut or bevel cut.

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.
