Simpson SUR1.81/11 SUR Galvanized Joist Hanger for 1-3/4 in. x 11-1/4 to 11-7/8 in. Engineered Wood, Skewed Right is a 45 deg.-skewed joist hanger from Simpson Strong-Tie engineered to provide reliable support underneath joists, rafters, or beams where a right-skewed connection is required. This U-shaped hanger encapsulates the top flange of the joist, eliminating the need for web stiffeners during standard installation, making it a practical and efficient solution for solid sawn and engineered wood construction applications.

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.
