The Simpson SULC46 Concealed Joist Hanger Skewed Left for 4x6 Lumber is a purpose-built connector designed to handle angled framing connections where a precise 45 deg. left skew is required. Its concealed header flange design keeps metal hardware out of sight in exposed framing conditions, making it a practical choice for residential and light commercial floor and roof systems where both structural integrity and clean visual lines are priorities. Fabricated from 16-gauge steel with a Zinc Galvanized G90 coating, this hanger is engineered to deliver dependable load transfer and corrosion resistance in demanding wood-frame construction applications.

Key Features

• 45 deg. Left Skew Orientation - Provides precise angular alignment for 4x6 members at angled joist-to-beam or joist-to-header connections, eliminating the need for field modifications that can compromise structural performance.
• Concealed Header Flanges - Flanges are hidden within the connection point, producing cleaner, more finished visible lines in exposed framing conditions where appearance is as important as function.
• 16-Gauge Steel Construction - Delivers the structural rigidity needed for reliable load transfer in residential and light commercial wood-frame floor and roof framing systems without adding unnecessary bulk to the connection.
• Zinc Galvanized G90 Coating - Factory-applied corrosion protection helps the hanger hold up in demanding framing environments, supporting long-term performance over the life of the structure.
• U-Shaped Hanger Profile for 4x6 Lumber - Sized and shaped specifically for 4x6 members, ensuring a secure, properly fitted connection without guesswork or adaptation on the job site.

Why This Product

• Engineered for a specific job - The SULC46 is purpose-designed for left-skewed 45 deg. connections in 4x6 wood-frame construction, so contractors get a connector that fits the application correctly from the start rather than forcing a general-purpose hanger to work at an angle.
• Aesthetics meet structural performance - The concealed header flange design addresses a common challenge in exposed framing: maintaining clean sight lines without sacrificing the load-carrying capability required in floor and roof systems.
• Domestic fabrication with proven corrosion protection - Built in the United States from 16-gauge steel with a G90 galvanized coating, this hanger is constructed to meet the durability expectations of professional framing work.
• Straightforward fastening requirements - Compatible with standard 16d common nails, the SULC46 fits into established framing workflows without requiring specialty fasteners or unusual installation steps.

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.
