The Simpson BA7.12/11.88 BA Top-Flange Hanger is a cost-effective structural connector built for double 3-1/2 in. x 11-7/8 in. engineered wood products and solid sawn lumber. Part of Simpson's BA series, this top-flange joist hanger is designed to carry medium loads with solid sawn lumber and higher loads with engineered wood products, making it a dependable choice for a wide range of structural framing applications. Its minimum and maximum nailing options give engineers and installers meaningful design versatility, while 12-gauge steel construction and a G90 zinc galvanized coating deliver the durability that demanding framing projects require.

Key Features

• Two-level embossment at the top flange provides increased stiffness - adds rigidity to the connection point, helping the hanger maintain structural integrity under load without relying on additional reinforcement.
• Full-height joist flange captures the top chord of the joist - prevents joist rotation and eliminates the need for web stiffeners, reducing labor and material costs during installation.
• Minimum and maximum nailing options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, giving designers flexibility to meet a wider range of project specifications with a single hanger model.
• Available for special order to accommodate sloped and/or skewed members - hangers may be modified for slopes and/or skews up to 45 deg., making this hanger adaptable to complex framing geometries beyond standard square installations.
• Made from 12-gauge steel - provides a robust structural foundation suited to the medium-to-high load demands of engineered lumber framing.
• Galvanized G90 zinc coating - delivers extra corrosion resistance, helping protect the connection over the life of the structure in moisture-prone framing environments.

Why This Product

• Engineered for both solid sawn and engineered wood - the BA series design carries medium loads with solid sawn lumber and higher loads with engineered wood products, so one hanger handles a broad range of common framing materials without compromise.
• Rotation prevention built in - the full-height joist flange captures the top chord to prevent rotation and eliminate the need for web stiffeners, simplifying the installation process and reducing the number of additional components required on the job.
• Flexible nailing for scalable load capacity - the ability to switch between minimum and maximum nailing patterns means installers can match the fastener schedule directly to the structural load requirement, making this hanger a practical choice across varied project conditions.
• Durable corrosion-resistant construction - 12-gauge steel combined with a G90 zinc galvanized finish means this top-flange joist hanger is built to hold up in the demanding conditions typical of structural framing applications.
