The Simpson SUR1.81/9 Skewed Right Joist Hanger from Simpson is a 45 deg.-skewed, U-shaped connector engineered to support solid sawn and engineered wood products in skewed framing applications. Sized for 1-3/4 in. x 9-1/4 to 9-1/2 in. members, this hanger encapsulates the top flange of the joist so no web stiffeners are required for standard installation, saving time and simplifying the connection. Built from 16-gauge steel with a G90 zinc galvanized finish, it delivers a strong, corrosion-resistant solution for angled floor and roof framing where a right-skewed connection is required.

Key Features

• Skewed right at 45 deg. with 40 deg. to 50 deg. field accommodation - the fixed skew angle handles a practical range of real-world framing conditions without modification, reducing layout headaches on the job site.
• Obround nail holes on the acute side - allow nails to be driven parallel to the joist, making fastening easier in the tight space created by the skewed angle and speeding up installation.
• Positive-angle nailing for engineered wood sizes - guides fasteners at the correct angle to prevent wood splitting, protecting the structural integrity of LVL and other engineered lumber members.
• U-shaped design encapsulates the top flange - eliminates the need for web stiffeners in standard installation, cutting material costs and reducing steps in the framing process.
• 16-gauge steel construction - provides a robust, load-bearing connection capable of handling the demands of structural wood framing applications.
• G90 zinc galvanized finish - offers corrosion resistance suited to treated lumber and exposed framing environments, helping the connector hold up over the life of the structure.
• Cannot be modified but accommodates a 40 deg. to 50 deg. skewed joist - the rigid, purpose-built geometry maintains consistent load transfer and eliminates guesswork when the as-built skew falls within the accepted range.

Why This Product

• Purpose-built for right-skewed connections - rather than bending or forcing a standard hanger, this fixed 45 deg. skewed-right design delivers a clean, engineered fit for angled joist-to-header connections, ensuring proper load transfer and a professional result.
• No web stiffeners required - the U-shaped profile wraps the top flange of the joist, so standard installations go in faster with fewer extra parts, keeping the framing schedule on track.
• Fastener flexibility built in - the hanger can be installed with either conventional nails or Strong-Drive SD Connector screws, letting contractors use the fastener type that best fits their tools and workflow without compromising the connection.
• Corrosion-resistant finish for long-term performance - the G90 galvanized coating makes this hanger a dependable choice in environments where moisture or treated lumber could degrade an uncoated connector over time.

Frequently Asked Questions

What is the difference between the SUR and SUL hangers?

The SUR and SUL hangers are identical in design except that the SUR is skewed 45 deg. to the right and the SUL is skewed 45 deg. to the left. Choose SUR when your joist frames into the header from the right side at a skewed angle.

What range of skew angles will the SUR1.81/9 accommodate?

While this hanger is designed at a fixed 45 deg. skew and cannot be modified, it will accommodate joists skewed between 40 deg. and 50 deg., providing a small degree of flexibility for field conditions.

Are web stiffeners required when installing the SUR1.81/9?

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

What fasteners are required to install the SUR1.81/9?

Install with (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).
