The Simpson SULC46 Concealed Joist Hanger is a 45-degree skewed-left, U-shaped hanger engineered to support 4x6 lumber members in wood-frame construction. Featuring concealed header flanges, this hanger delivers cleaner, more finished visible lines in exposed conditions - making it an ideal choice where aesthetics matter as much as structural performance. Manufactured in the United States from 16-gauge steel with a Zinc Galvanized G90 coating, the SULC46 is built to provide lasting corrosion resistance and reliable load transfer in demanding framing applications.

Key Features

• 45-Degree Skewed Left: Designed specifically for left-skewed framing connections, providing precise angular alignment for 4x6 members.
• Concealed Header Flanges: Flanges are hidden within the connection, resulting in cleaner visible lines ideal for exposed architectural conditions.
• U-Shaped Design: Sturdy U-shape provides solid three-sided support for the joist member, enhancing load transfer and connection stability.
• 16-Gauge Steel Construction: Heavy-duty gauge delivers high strength while maintaining formability and consistent dimensions.
• Zinc Galvanized G90 Coating: Factory-applied G90 galvanized finish provides corrosion resistance suitable for standard interior and sheltered framing environments.
• Made in the United States: Manufactured domestically to strict quality standards.

Frequently Asked Questions

What lumber size is the SULC46 designed to support?

The Simpson SULC46 is engineered specifically to support 4x6 lumber members in wood-frame construction.

What is the skew direction and angle of this joist hanger?

The SULC46 is skewed left at a 45-degree angle, making it designed specifically for left-skewed framing connections that require precise angular alignment.

What gauge steel is used, and what corrosion protection does this hanger have?

The SULC46 is constructed from 16-gauge steel with a factory-applied Zinc Galvanized G90 coating, which provides corrosion resistance suitable for standard interior and sheltered framing environments.

What makes this hanger suitable for exposed or architectural applications?

The SULC46 features concealed header flanges, meaning the flanges are hidden within the connection rather than visible on the face. This results in cleaner, more finished visible lines, making it well suited for exposed conditions where aesthetics matter alongside structural performance.
