The Simpson Double 2x10 Concealed Flange Joist Hanger Skewed Left HSULC210-2 is a heavy-duty connector engineered to carry double 2x10 members at a precise 45 deg. left skew in wood-framed construction. Built in a heavy U-shape with concealed header flanges, it suits both structural performance and architectural applications where visible framing lines matter. Fabricated from 14-gauge steel with a zinc galvanized G90 coating, this hanger is built to handle demanding residential and commercial job sites with lasting corrosion resistance.

Key Features

• 45 deg. Left Skew with Flexible Tolerance - Accommodates connections skewed between 40 deg. and 50 deg., giving framers practical flexibility when field conditions are not perfectly on-angle.
• Concealed Header Flanges - Flanges tuck behind the header so they stay out of sight, producing cleaner finished lines in exposed architectural framing without sacrificing load capacity.
• Heavy U-Shape Body - The robust U-shaped profile cradles double 2x10 members securely, distributing load evenly and reducing stress concentrations at the connection point.
• 14-Gauge Construction with G90 Zinc Galvanized Coating - Heavy-gauge steel delivers the strength required for double-member joist applications, while the G90 galvanized finish resists corrosion in moisture-prone framing environments.
• Square or Bevel Cut Joist Compatibility - Accepts both square-cut and bevel-cut joist ends, reducing the need for precise pre-cutting and saving time during installation.
• Multiple Accepted Fastener Types - Compatible with Strong-Drive SD connector screws as well as standard nails, so installers can use the fastener type best suited to their tools and site conditions.

Why This Product

• Purpose-Built for Left-Skewed Double-Member Connections - Where a standard straight hanger simply will not fit, this connector provides a dedicated, correctly angled seat for double 2x10 joists skewed left, eliminating field improvisation and keeping the connection code-compliant.
• Architectural-Grade Appearance in Structural Hardware - The concealed flange design means the hanger works equally well in exposed ceiling and open-beam applications, giving builders a single product that satisfies both the structural engineer and the architect.
• Simpson Engineering and Domestic Fabrication - Backed by Simpson's reputation for connector engineering and made in the United States, the HSULC210-2 arrives with the documentation, load tables, and quality consistency that contractors and inspectors rely on.
• Versatile Fastener Acceptance Streamlines Installation - Support for both screw and nail fastener schedules means crews are not locked into a single fastener type to reach rated loads, keeping installation straightforward across different project setups.

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.
