The Simpson SUL410 Joist Hanger Skewed Left for 4x10 from Simpson is a 16-gauge steel framing connector engineered to create a reliable 45 deg. angled connection between a joist and header in wood construction. Built for left-skewed framing layouts, this hanger accommodates nominal 4x10 or 4x12 lumber and accepts a range of skew angles from 40 deg. to 50 deg., giving installers flexibility in real-world field conditions. A G90 galvanized finish delivers lasting corrosion resistance, making this connector a dependable choice for structural framing applications where long-term performance matters.

Key Features

• SUL = skewed left orientation - provides a precise 45 deg. connection between a joist and header, ensuring correct geometry for left-skewed framing layouts without modification
• Accommodates a 40 deg. to 50 deg. skew - allows for minor variation in field conditions so installers can achieve a secure fit even when angles are not perfectly uniform
• Square cut or bevel cut joist end accepted - reduces material waste and simplifies cutting in the field, saving time during installation
• Angled nail slots direct nails for proper installation - guides fasteners into the correct position automatically, helping ensure a code-compliant connection without guesswork
• Made from 16-gauge steel - provides the structural rigidity needed for load-bearing joist-to-header connections in residential and light commercial framing
• G90 zinc galvanized finish - delivers enhanced corrosion resistance suited for demanding structural environments where moisture exposure is a concern

Why This Product

• Purpose-built for angled framing - unlike standard square joist hangers, the SUL410 is specifically designed for 45 deg. left-skewed connections, eliminating the need for field fabrication or makeshift solutions when the framing layout calls for an angled joist-to-header joint
• Flexibility without compromise - the 40 deg. to 50 deg. skew tolerance and compatibility with both square cut and bevel cut joist ends give contractors practical options on the job site while maintaining structural integrity
• Built-in installation guidance - angled nail slots take the uncertainty out of fastener placement, helping ensure every connection meets installation requirements from the first nail driven
• Durable galvanized construction from a trusted brand - Simpson's G90 galvanized, 16-gauge steel construction means this hanger is built to hold up over time in the structural framing applications where consistent performance is essential

Frequently Asked Questions

What does "SUL" mean and how does it differ from "SUR"?

SUL stands for skewed left, meaning the hanger is angled 45 deg. to the left to connect a joist to a header. The SUR version is identical in design but is skewed 45 deg. to the right instead. Choosing the correct orientation depends on the direction of the skew in your framing layout.

What range of skew angles does the SUL410 accommodate?

The SUL410 will normally accommodate a 40 deg. to 50 deg. skew, making it suitable for applications requiring a consistent 45 deg. connection with slight variation in field conditions.

Does the joist need to be cut at a specific angle for installation?

No special cut is required. The joist end may be square cut or bevel cut, providing flexibility during installation and reducing material waste in the field.

What fasteners are required to install the SUL410?

Installation requires 16d common nails. The hanger features angled nail slots that direct nails into the correct position to ensure a proper, code-compliant installation.
