The Simpson SUL1.81/9 SUL Galvanized Joist Hanger for 1-3/4 in. x 9-1/4 to 9-1/2 in. Engineered Wood, Skewed Left is a heavy-duty 45 deg.-skewed hanger engineered by Simpson Strong-Tie to deliver reliable support for solid sawn and engineered wood joists in wood construction applications. This U-shaped hanger encapsulates the top flange of the joist, eliminating the need for web stiffeners during standard installation and providing a strong, secure connection at a precise left-skew angle.

Key Features

• SUL = skewed left - hanger is fixed at a 45 deg. left skew angle
• Features obround nail holes on the acute side, allowing nails to be easily installed parallel to the joist
• These hangers cannot be modified but will accommodate a 40 deg. to 50 deg. skewed joist
• Features positive-angle nailing for engineered wood sizes to prevent wood splitting and to speed installation
• Seat width: 1-13/16 in.
• Joist size: 1-3/4 in. x 9-1/4 to 9-1/2 in.
• Made from 16-gauge steel
• Galvanized (G90) for corrosion resistance
• U-shaped design encapsulates the top flange of the joist - no web stiffeners required for standard installation
• Designed to support both solid sawn and engineered wood products

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.
