The Simpson HSULC46 Concealed Flange Joist Hanger Skewed Left 4x6 is a 14-gauge skewed joist hanger engineered by Simpson to connect 4x6 lumber members at a 45 deg. left skew in wood-frame construction. Its concealed header flanges and flexible angular range make it a reliable choice for both structural and exposed framing applications where a clean finished appearance and precise angular alignment are equally important.

Key Features

• 45 deg. left-skewed design - delivers precise angular alignment for 4x6 members without requiring field modification, saving layout time on angled framing connections.
• Concealed header flanges - keep the connection hardware hidden behind the header, producing clean, professional visible lines in exposed framing conditions.
• A2 acute flange configuration - the flange turns inward to accommodate end-of-wall installations, expanding the range of job-site applications this hanger can handle.
• Top-flange encapsulation design - fully wraps the top flange of the joist so no web stiffeners are required for standard installation, reducing labor and material costs.
• Accepts both square-cut and bevel-cut joist ends - gives installers flexibility to work with how lumber arrives on site without additional cutting requirements.
• Angular tolerance of 40 deg. to 50 deg. - accommodates real-world framing variations without any alteration to the hanger, reducing the risk of a misfitting connection.
• Obround nail holes - allow some positioning adjustment during installation, making it easier to align the hanger accurately before final fastening.

Why This Product

• Purpose-built for skewed connections - the fixed 45 deg. left-skew geometry and 40 deg. to 50 deg. tolerance range means this hanger handles angled 4x6 framing situations that a standard straight hanger simply cannot address, reducing the need for costly custom fabrication.
• Aesthetics and structure in one component - concealed flanges eliminate exposed hardware on visible header faces, making this hanger equally suitable for finish-quality exposed framing and utilitarian structural applications without compromise.
• Simplified installation with no added hardware - because the hanger encapsulates the joist top flange, web stiffeners are not needed for standard installation, cutting down on parts and installation steps at the jobsite.
• Domestic quality from a trusted brand - made in the United States by Simpson, this hanger comes from a manufacturer with a long track record in structural connector engineering, giving contractors and builders confidence in consistent quality and material standards.

Frequently Asked Questions

What fasteners are required to install the HSULC46?

Installation requires either #9 x 2-1/2" Strong-Drive SD Connector screws or 0.162" x 3-1/2" nails. All round and obround nail holes must be filled with the specified fasteners to achieve table loads. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity.

Does the joist need to be bevel cut to match the 45-degree skew angle?

No. The joist end may be either square cut or bevel cut - both are acceptable for standard installation with the HSULC46.

Can the HSULC46 hanger be field-modified to adjust the skew angle?

No. These hangers cannot be modified. However, they are designed to accommodate a joist skewed anywhere from 40 degrees to 50 degrees, providing a practical range of angular flexibility without any alteration to the hanger.

What is the difference between the HSULC and HSURC hangers?

The HSULC and HSURC are identical hangers except for their skew direction. The HSULC is skewed 45 degrees to the left, while the HSURC is skewed 45 degrees to the right. Both feature concealed header flanges and support 2x and 4x members in wood construction.
