The Simpson SUR1.81/11 SUR Galvanized Joist Hanger is a 45 deg.-skewed, U-shaped connector from Simpson Strong-Tie, purpose-built to deliver reliable load transfer where a right-skewed joist connection is required in solid sawn and engineered wood construction. Designed to encapsulate the top flange of the joist, this hanger eliminates the need for web stiffeners during standard installation, saving time and reducing material costs on the job. Made from 16-gauge steel with a G90 zinc galvanized finish, it is built to hold up in demanding framing conditions while accommodating a range of 40 deg. to 50 deg. skewed joists without field modification.

Key Features

• Skewed right at 45 deg. - delivers a precise, pre-engineered right-hand skew connection so framers do not have to fabricate or force an angle in the field
• Accommodates 40 deg. to 50 deg. skewed joists without modification - provides built-in tolerance that covers real-world framing variances, reducing rework and keeping projects on schedule
• U-shaped design encapsulates the top flange of the joist - eliminates the requirement for web stiffeners in standard installation, cutting down on extra hardware and labor
• Obround nail holes on the acute side - allow nails to be installed parallel to the joist in a tight space, making fastening faster and more accurate where clearance is limited
• Positive-angle nailing for engineered wood sizes - helps prevent wood splitting and speeds up installation, which is especially important when working with LVL and other engineered lumber products
• 16-gauge steel construction - provides the structural rigidity needed for heavy joist and rafter applications while maintaining compatibility with standard framing fasteners
• G90 zinc galvanized finish - offers a corrosion-resistant coating suited for treated lumber environments and other applications where moisture exposure is a concern

Why This Product

• No field modification needed - unlike hangers that require bending or cutting to achieve a skewed connection, this connector arrives pre-set at 45 deg. right and accommodates a 40 deg. to 50 deg. range out of the box, keeping installation straightforward and code-compliant
• Engineered specifically for engineered wood - the positive-angle nailing design is optimized for LVL and other engineered lumber products sized at 1-3/4 in. x 11-1/4 to 11-7/8 in., reducing the risk of splitting and protecting the structural integrity of the member
• Two fastener options for jobsite flexibility - install with face nails and joist nails, or swap to Strong-Drive SD Connector screws, giving contractors the ability to match the fastener method to the tools and materials already on hand
• Trusted Simpson Strong-Tie engineering, made in the United States - built to the quality and load-rating standards that structural framers and building inspectors recognize, providing confidence from rough framing through final inspection

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. Choose the model that matches the direction of your skewed joist connection.

Can the SUR1.81/11 be field-modified to fit a different skew angle?

No, these hangers cannot be modified. However, the SUR1.81/11 is designed to accommodate a range of 40 deg. to 50 deg. skewed joists without any alteration.

What fasteners are required to install the SUR1.81/11?

Installation requires either (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 SUR1.81/11 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, simplifying the fastening process in tight-angle applications and contributing to faster, more accurate installation.

Note: Product dimensions and/or Screw or Nail holes may differ from picture. See item description for specifications.
