Product Description
The Simpson BA4.12/11.88 Top-Flange Joist Hanger is a cost-effective connector designed for double 2 in. x 11-7/8 in. engineered wood and solid sawn lumber framing applications. Built from 12-gauge steel with a G90 zinc galvanized finish, this top-flange hanger is engineered to carry medium loads with solid sawn lumber and higher loads with engineered wood products - giving framers a single, versatile solution for floor and roof framing systems where reliable joist-to-header connections are critical.
Key Features
- Two-level embossment at the top flange - increases stiffness at the connection point, improving overall structural integrity without requiring additional reinforcement
- Full-height joist flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, saving both time and materials during installation
- Minimum and maximum nailing options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, giving designers and builders flexibility to meet a range of project specifications
- Compatible with sloped and/or skewed members - accommodates angled framing conditions, making this hanger suitable for more complex roof and floor framing layouts
- 12-gauge steel construction - delivers the structural strength required for medium to higher load engineered wood product connections
- G90 zinc galvanized finish - provides extra corrosion resistance, extending the service life of the connection in demanding framing environments
Why This Product
- Engineered wood and solid sawn lumber versatility - the BA series is specifically designed to perform across both engineered wood products and solid sawn lumber, with load capacity that scales based on nailing configuration, making it a practical choice for a wide range of residential and light commercial framing projects
- Built-in rotation control without extra hardware - the full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners, which simplifies installation and reduces the number of components required on the job site
- Design flexibility through nailing options - with distinct minimum and maximum nailing targets, structural designers can dial in load capacity to match specific project demands without switching to a different hanger model
- Corrosion-resistant finish for long-term performance - the G90 galvanized coating offers extra protection against corrosion, making this hanger a dependable choice where moisture exposure or environmental conditions could compromise an uncoated connector over time

Frequently Asked Questions
What member size is this hanger designed to fit?
This hanger is designed specifically for a double 2 in. x 11-7/8 in. framing member, including both engineered wood products and solid sawn lumber of that dimension.
What fasteners are required to install this hanger?
Installation requires 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, allowing minimum nailing to target moderate load demands and maximum nailing to achieve higher load capacity.
Does this hanger require web stiffeners during installation?
No. The full-height joist flange captures the top chord of the joist to prevent rotation, which eliminates the need for web stiffeners and simplifies the installation process.
Can this hanger be used for sloped or skewed framing applications?
The standard BA4.12/11.88 is designed for square installations, but it is available as a special order to accommodate sloped and/or skewed members. Contact your supplier to inquire about special-order configurations for non-standard framing angles.
