The Simpson SUL Galvanized Joist Hanger for 1-3/4 in. x 9-1/4 to 9-1/2 in. Engineered Wood, Skewed Left is a fixed 45 deg. left-skew hanger from Simpson designed to deliver reliable support for solid sawn and engineered wood joists in wood-frame construction. Its U-shaped body encapsulates the top flange of the joist, so no web stiffeners are required for standard installation, saving time and simplifying the connection at angled framing conditions.

Key Features

• Fixed 45 deg. left-skew design (SUL) - positions the hanger precisely for left-skewed framing layouts, accommodating joist angles from 40 deg. to 50 deg. without any field modification required
• Obround nail holes on the acute side - allow nails to be driven parallel to the joist, reducing installation difficulty in tight or angled framing situations
• Positive-angle nailing for engineered wood sizes - helps prevent wood splitting during fastening and speeds up the installation process on the jobsite
• U-shaped body encapsulates the joist top flange - eliminates the need for web stiffeners in standard installations, reducing material and labor requirements
• Made from 16-gauge steel - provides a sturdy, load-capable connection suitable for structural framing applications
• G90 zinc galvanized finish - offers corrosion resistance to help the hanger hold up in demanding construction environments

Why This Product

• Purpose-built for skewed joist connections - unlike field-skewable hangers that require bending or adjustment, this hanger arrives ready for 45 deg. left-skew installations and accepts a 40 deg. to 50 deg. range, giving contractors a reliable, consistent fit without extra steps on the job
• Engineered for engineered wood - the positive-angle nailing feature is specifically designed for engineered wood member sizes, reducing the risk of wood splitting and keeping installation moving efficiently on projects using LVL or similar products
• Dual fastener options for jobsite flexibility - the hanger can be installed with either nails or Simpson Strong-Drive SD Connector screws, so crews can work with whichever fastener method suits their tools and project requirements
• No web stiffeners needed - the U-shaped encapsulating design simplifies standard installation by removing a common extra step, cutting down on both material costs and time spent at each connection point

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. Both are U-shaped hangers that encapsulate the top flange of the joist and require no web stiffeners for standard installation.

Can the SUL1.81/9 be field-modified to adjust the skew angle?

No, these hangers cannot be modified in the field. However, the SUL1.81/9 will accommodate a joist skewed anywhere from 40 deg. to 50 deg., providing a degree of flexibility around its fixed 45 deg. left-skew design.

What fasteners are required to install the SUL1.81/9?

Installation requires either (12) 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 (14) #9 x 1-1/2 in. Strong-Drive SD Connector screws (SD9112).

What type of wood is the SUL1.81/9 designed to support?

The SUL1.81/9 is designed to support both solid sawn and engineered wood products with a member size of 1-3/4 in. x 9-1/4 to 9-1/2 in. It features positive-angle nailing specifically suited to engineered wood sizes to help prevent wood splitting and speed up installation.
