The Simpson BA2.37/20 BA Series Top-Flange Joist Hanger is a cost-effective, high-performance connector engineered for both engineered wood and solid sawn lumber applications. Sized for a 2-5/16 in. x 20 in. member, this hanger is built to carry medium loads with solid sawn lumber and higher loads with engineered wood products. Fabricated from 12-gauge steel with a G90 zinc galvanized finish for enhanced corrosion resistance, the BA2.37/20 delivers structural reliability and design flexibility through its min./max. nailing options - making it a versatile solution for a wide range of framing applications.

Key Features

• Two-Level Top-Flange Embossment: Provides increased stiffness at the top flange for a stronger, more rigid connection.
• Full-Height Joist Flange: Captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, streamlining installation.
• Min./Max. Nailing Options: Minimum nailing targets moderate load demands, while maximum nailing allows higher loads - giving engineers and contractors greater design versatility.
• 12-Gauge Steel Construction: Heavy-duty gauge steel provides robust structural performance for demanding framing applications.
• G90 Zinc Galvanized Coating: Offers extra corrosion resistance for long-term durability in exposed or treated-lumber environments.
• Sloped & Skewed Options: Available for special order to accommodate sloped and/or skewed members.
• Made in the United States: Domestically manufactured to consistent quality standards.

Approved Applications

The BA2.37/20 top-flange joist hanger is designed for use in the following structural framing applications:

• Engineered Wood Products (EWP): Optimized to carry higher loads when used with engineered wood such as LVL, LSL, PSL, and I-joists sized at 2-5/16 in. x 20 in.
• Solid Sawn Lumber: Suitable for medium-load applications with dimensional solid sawn lumber framing members.
• Floor & Roof Framing Systems: Ideal for residential and light commercial floor and roof framing where top-flange connectivity is required.
• Sloped & Skewed Framing (Special Order): Can be modified to accommodate sloped and/or skewed members for non-standard framing configurations.

Installation Information

Install with 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist. The full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners. Select minimum or maximum nailing patterns based on your load requirements.
