The Simpson SULC210-2 Concealed Joist Hanger Skewed Left for Double 2x10 is a purpose-built connector from Simpson designed to join double 2x10 joist members to a header or beam at a precise 45 deg. left angle in wood-frame construction. With concealed header flanges and a galvanized steel build, this skewed hanger delivers both structural reliability and a cleaner finished appearance in exposed framing conditions - making it a dependable choice for residential and light commercial floor and roof framing projects that demand angled connections without sacrificing aesthetics.

Key Features

• 45 deg. Left Skew Configuration - Engineered specifically for left-hand angled framing, this hanger lets double 2x10 joists meet a header at a true 45 deg. left offset, eliminating the guesswork and field modification that come with trying to adapt a straight or right-skewed connector.
• Concealed Header Flanges - The flanges seat behind the header rather than wrapping around the face, keeping hardware out of sight in exposed framing conditions where a neat, finished look is important alongside structural performance.
• Double 2x10 Member Support - Sized and rated specifically for doubled joist members, this hanger removes the need to stack or modify single-member hangers, giving installers a single, code-friendly solution for heavier framing assemblies.
• Zinc Galvanized G90 Coating - The G90 galvanized finish provides a meaningful layer of corrosion resistance, helping the connector hold up in the range of wood-framing environments typically encountered in residential and light commercial construction.
• 16-Gauge Steel Construction - The heavier gauge delivers the rigidity needed to maintain alignment during installation and support the loads associated with doubled floor or roof joist applications.
• Made in the United States - Produced domestically under Simpson quality controls, ensuring consistent dimensional accuracy and coating quality across every unit.

Why This Product

• Solves a Specific Framing Challenge - Angled joist connections at 45 deg. left cannot be handled cleanly by a standard straight hanger. The SULC210-2 is built for exactly this condition, reducing the need for field improvisation and helping keep installations code-compliant and structurally sound.
• Aesthetic Advantage in Exposed Applications - Because the header flanges are concealed, this hanger is a natural fit for visible ceiling or deck framing where exposed hardware would detract from the finished appearance - a practical benefit that a face-mount hanger simply cannot offer.
• Right-Left Pairing Simplifies Planning - The SULC210-2 is the direct left-hand counterpart to the SURC right-skewed hanger series, making it straightforward to spec and order matching connectors for symmetrical or opposing 45 deg. connections within the same framing layout.
• Broad Application Range - Approved for both residential and light commercial floor and roof framing, this hanger covers a wide range of project types with a single, well-defined connector rather than requiring custom or specialty fabrication.

Frequently Asked Questions

What is the difference between the SULC and SURC series?

The SULC and SURC hangers are identical in design except for skew direction. The SURC is skewed 45 degrees to the right, while the SULC is skewed 45 degrees to the left. The SULC210-2 is the left-skewed version designed for double 2x10 members.

What fasteners are required for the SULC210-2?

Installation requires 16d common nails and 16d x 2-1/2 in. nails. Refer to applicable load tables and building codes to confirm the required quantity and placement for your specific application.

What coating does the SULC210-2 have?

The SULC210-2 features a Zinc Galvanized G90 coating, which provides corrosion resistance for use in standard wood-framing applications.

Are the header flanges visible after installation?

No. The SULC210-2 is designed with concealed header flanges, meaning the flanges are hidden behind the header after installation. This provides cleaner visible lines, making it well-suited for exposed fr
