The Simpson SUL Galvanized Joist Hanger for 1-3/4 in. x 11-1/4 to 11-7/8 in. Engineered Wood, Skewed Left by Simpson is a fixed 45 deg.-skewed, U-shaped connector engineered to support solid sawn and engineered wood products in wood construction applications where joists meet a header or beam at an angle. The SUL design encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installations and delivering a strong, structurally reliable connection for angled framing conditions.

Key Features

• Fixed 45 deg. left skew (SUL) with 40 deg. to 50 deg. tolerance - accommodates real-world framing variations around the nominal angle without requiring field modification, keeping installations code-consistent and accurate.
• Obround nail holes on the acute side - allow nails to be driven parallel to the joist even in tight framing conditions, reducing installation difficulty and saving time on the job site.
• Positive-angle nailing for engineered wood sizes - guides fasteners at the correct angle to prevent splitting of engineered lumber, protecting the structural member and speeding up the nailing process.
• U-shaped profile encapsulates the joist top flange - provides continuous support underneath the joist or rafter and removes the requirement for web stiffeners in standard installations, simplifying the overall connection detail.
• Made from 16-gauge steel - delivers the structural thickness needed for demanding load-transfer applications in residential and light commercial wood framing.
• Zinc Galvanized G90 coating - provides corrosion resistance suited to the environments where treated lumber and engineered wood products are commonly used, helping the connector maintain long-term integrity.

Why This Product

• Purpose-built for angled framing conditions - unlike field-skewable hangers that require bending or adjustment on site, this hanger arrives pre-formed at a precise 45 deg. left skew, delivering consistent geometry and reducing the risk of installer error in complex framing layouts.
• Engineered wood compatibility with built-in split prevention - the positive-angle nailing feature is specifically designed for engineered wood member sizes, addressing a common concern when fastening into LVL and similar products and helping preserve the integrity of high-value structural materials.
• Faster, cleaner installation - the combination of obround nail holes on the acute side and top-flange encapsulation means fewer workarounds during nailing and no need to add supplemental web stiffeners, cutting labor time on angled joist connections.
• Made in the United States to Simpson quality standards - produced domestically by Simpson, a widely recognized name in structural connectors, giving builders and inspectors confidence in the product's consistency and traceability.

Frequently Asked Questions

What is the difference between the SUR and the SUL hanger?

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. Both are U-shaped hangers that encapsulate the top flange of the joist and support solid sawn and engineered wood products.

Can the SUL1.81/11 be field-modified to adjust the skew angle?

No, these hangers cannot be modified in the field. However, the SUL1.81/11 is designed to accommodate joists skewed between 40 deg. and 50 deg., providing a degree of flexibility around its fixed 45 deg. skew angle.

What fasteners are required to install the SUL1.81/11?

Install with (16) 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 (18) #9 x 1-1/2 in. Strong-Drive SD Connector screws (SD9112).

Why does the SUL1.81/11 feature obround nail holes on the acute side?

The obround nail holes on the acute side are specifically designed to allow nails to be easily installed parallel to the joist, improving installation efficiency and accuracy, particularly in tight or angled framing conditions.
