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.
