Simpson Double 2x10 Concealed Flange Joist Hanger Skewed Left - HSULC210-2

The Simpson HSULC210-2 is a heavy-duty, 45 deg.-skewed concealed flange joist hanger engineered to support double 2x10 members in wood-framed construction. Skewed left at a precise 45 deg. angle, this hanger features a heavy U-shaped body with concealed header flanges that deliver cleaner, more finished visible lines in exposed architectural conditions. Manufactured in the United States, the HSULC210-2 is built to perform where both structural integrity and aesthetic presentation matter. Its 14-gauge zinc galvanized G90 coating provides reliable corrosion resistance in demanding environments.

Key Features

• 45 deg. Left Skew: Designed specifically for supporting members skewed to the left; accommodates joists skewed between 40 deg. and 50 deg.
• Concealed Header Flanges: Provides cleaner visible lines in exposed conditions without sacrificing structural performance
• A2 (Acute) Flange Design: Flange is turned inward to accommodate end-of-wall installation scenarios
• No Web Stiffeners Required: Encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installations
• Obround Nail Holes on Acute Side: Allows nails to be easily installed parallel to the joist for straightforward fastening
• Triangle Holes for Uplift: Triangle holes in the joist flange may be filled with additional fasteners for increased uplift capacity
• Non-Modifiable Design: These hangers cannot be modified but will accommodate a 40 deg.- to 50 deg.-skewed joist
• 14-Gauge Steel: Heavy construction for high-load applications in residential and commercial wood framing
• G90 Zinc Galvanized Coating: Offers durable corrosion protection for long-term performance
• Flexible Joist End Cut: The joist end may be square cut or bevel cut

Installation

The HSULC210-2 requires specific fasteners to achieve rated table loads. Accepted fasteners include:

• #9 x 2-1/2" Strong-Drive SD Connector Screws
• 0.162" x 3-1/2" Nails and 0.162" x 2-1/2" Nails

Fill all round and obround nail holes with the specified fasteners to achieve table loads. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity. The joist end may be square cut or bevel cut.

Frequently Asked Questions

What size and type of lumber is this joist hanger designed to support?

The HSULC210-2 is engineered specifically to support double 2x10 members in wood-framed construction.

What angle is this hanger skewed, and does it accommodate slight variations in skew angle?

This hanger is skewed left at a precise 45 deg. angle and is designed to accommodate joists skewed between 40 deg. and 50 deg., allowing for minor variations in the field.

Are web stiffeners required when installing this joist hanger?

No, web stiffeners are not required. The HSULC210-2 encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installations.

What corrosion protection does this hanger provide, and can it be modified on the job site?

The HSULC210-2 features a 14-gauge zinc galvanized G90 coating for reliable corrosion resistance. However, this hanger cannot be modified on the job site - it is a non-modifiable design intended to be used as manufactured.
