Product Description
The Simpson BA2.37/20 Top-Flange Joist Hanger is a cost-effective structural connector designed for 2-5/16 in. x 20 in. engineered wood and solid sawn lumber framing applications. Built from 12-gauge steel with a G90 zinc galvanized finish for enhanced corrosion resistance, this top-flange hanger is engineered to carry medium loads with solid sawn lumber and higher loads with engineered wood products. Its min./max. nailing options give engineers and contractors the design versatility needed to meet a broad range of structural load requirements in floor and roof framing systems.
Key Features
- Two-Level Top-Flange Embossment - increases stiffness at the top flange, giving the connection greater rigidity and structural stability under load.
- Full-Height Joist Flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, reducing material costs and simplifying installation.
- Min./Max. Nailing Options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, so one hanger model adapts to multiple design scenarios.
- 12-Gauge Steel Construction - provides the structural strength required for demanding residential and light commercial framing applications without unnecessary bulk.
- G90 Zinc Galvanized Finish - offers enhanced corrosion resistance, making this hanger suitable for use in environments where moisture exposure is a concern.
- Sloped and Skewed Member Compatibility (Special Order) - available to accommodate sloped and/or skewed members, supporting non-standard framing configurations when standard geometry is not an option.
Why This Product
- Optimized for Engineered Wood Products - the BA2.37/20 is specifically sized for 2-5/16 in. x 20 in. engineered wood members such as LVL, LSL, PSL, and I-joists, delivering higher load capacity where engineered lumber is used - a key advantage over hangers designed only for dimensional lumber.
- Rotation Prevention Built In - the full-height joist flange captures the top chord of the joist directly, eliminating joist rotation without requiring additional web stiffeners, which saves time and reduces installed cost.
- One Hanger, Multiple Load Levels - the min./max. nailing design means a single hanger can serve both moderate- and higher-load applications, reducing the number of SKUs a contractor needs to stock on the jobsite.
- Made in the United States with Premium Corrosion Protection - domestic manufacturing combined with a G90 galvanized coating means consistent quality and long-term durability in both interior and moisture-exposed framing environments.

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.

Frequently Asked Questions
What size joist is the BA2.37/20 designed to fit?
The BA2.37/20 is sized for a 2-5/16 in. x 20 in. member. It is compatible with both engineered wood products and solid sawn lumber of that dimension, carrying medium loads with solid sawn lumber and higher loads with engineered wood products.
What nails are required to install this joist hanger?
Install the BA2.37/20 using 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 hanger offers minimum and maximum nailing options - minimum nailing targets moderate load demands, while maximum nailing allows higher loads.
What material and finish is the BA2.37/20 made from?
The BA2.37/20 is fabricated from 12-gauge steel with a G90 zinc galvanized finish, which provides extra corrosion resistance for long-term durability in exposed or treated-lumber environments.
Can the BA2.37/20 be used for sloped or skewed framing applications?
The BA2.37/20 in its standard configuration is designed for straight framing, but it is available for special order to accommodate sloped and/or skewed members, making it adaptable for a wider range of framing conditions.
