The Simpson SUL1.81/14 SUL Galvanized Joist Hanger is a 45 deg. left-skewed hanger from Simpson designed to support solid sawn and engineered wood products in angled wood framing applications. Its U-shaped profile encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installation and delivering a strong, reliable connection wherever a 1-3/4 in. x 14 in. joist meets a header at a left-skewed angle.

Key Features

• 45 deg. left-skewed design (SUL) - purpose-built for left-angled joist connections, removing the guesswork and field fabrication that come with trying to adapt a straight hanger to an angled application
• Accommodates a 40 deg. to 50 deg. skew range - provides real-world installation flexibility so minor framing variations do not require a different hanger or field modification
• Cannot be field-modified - the fixed geometry ensures a consistent, code-compliant connection every time, reducing the risk of installer error on the job site
• Obround nail holes on the acute side - allow nails to be driven parallel to the joist in a tight corner where a standard round hole would make fastening difficult, speeding up installation
• Positive-angle nailing for engineered wood sizes - helps prevent wood splitting during fastener installation, protecting the structural integrity of LVL and other engineered lumber
• U-shaped profile encapsulates the top flange - no web stiffeners are required for standard installation, simplifying the build and reducing material costs
• Made from 16-gauge steel - delivers the structural rigidity needed to carry load at a skewed connection without adding unnecessary bulk
• G90 zinc galvanized finish - provides corrosion resistance suitable for treated-lumber environments and exposed framing conditions, extending the service life of the connection

Why This Product

• Engineered specifically for skewed framing - unlike field-bent or modified hangers, the SUL1.81/14 is factory-set at 45 deg. left and validated to handle 40 deg. to 50 deg. skew angles, giving structural confidence that a makeshift solution cannot match
• Faster, cleaner installation for engineered lumber - positive-angle nailing and obround nail holes work together to make fastening straightforward even in tight, angled spaces, cutting down on labor time for 1-3/4 in. engineered wood members
• No extra hardware required - the encapsulating U-shape eliminates web stiffeners from the standard installation, reducing parts count and keeping the connection detail simple
• Built for long-term durability - G90 galvanized 16-gauge steel construction holds up in the demanding conditions common to exposed or pressure-treated-lumber framing, protecting the connection for the life of the structure

Frequently Asked Questions

What is the difference between the SUR and SUL hangers?

The SUR and SUL hangers are identical in design except for their skew direction. The SUR is skewed 45 deg. to the right, while the SUL is skewed 45 deg. to the left. Choose the SUL when your joist runs to the left of the header at a 45 deg. angle.

Can the SUL1.81/14 be field-modified to adjust the skew angle?

No. These hangers cannot be modified in the field. However, the SUL1.81/14 will accommodate a joist skewed anywhere from 40 deg. to 50 deg., providing a degree of flexibility within that range without requiring any alteration to the hanger.

Are web stiffeners required when using the SUL1.81/14?

No. Because the U-shaped profile encapsulates the top flange of the joist, web stiffeners are not required for standard installation, simplifying the installation process.

What fasteners are required to install the SUL1.81/14?

Install with (20) 0.162 x 3-1/2 in. nails in the face and (2) 0.148 x 1-1/2 in. nails in the joist, OR (22) #9 x 1-1/2 in. Strong-Drive SD Connector screws (SD9112).
