The Simpson BA4.28/11.88 Top-Flange Joist Hanger is a cost-effective connector built for both engineered wood and solid sawn lumber framing applications. Sized for a double 2-1/4 in. x 11-7/8 in. member, it is engineered to carry medium loads with solid sawn lumber and higher loads with engineered wood products, making it a versatile choice across a wide range of structural framing conditions. Min./max. nailing options give designers and installers the flexibility to dial in the right load capacity for the job, while 12-gauge steel construction and a G90 zinc galvanized finish deliver the structural integrity and corrosion resistance that demanding framing connections require.

Key Features

• Two-level embossment at the top flange - provides increased stiffness at the connection point, improving overall structural performance without adding bulk.
• Full-height joist flange design - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, saving time and reducing material costs on the job site.
• Min./max. nailing options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, giving engineers and builders the design versatility to meet varying load requirements with a single hanger model.
• Available for sloped and/or skewed member configurations - accommodates non-standard framing angles, expanding the range of applications this hanger can serve on complex or custom projects.
• 12-gauge steel construction - delivers the structural strength needed for medium-to-higher load joist connections in both residential and commercial framing.
• G90 zinc galvanized finish - provides extra corrosion resistance, making this hanger suitable for use in environments where moisture exposure is a concern.

Why This Product

• One hanger, two load levels - the min./max. nailing design means a single hanger model can address a broader range of structural load demands, reducing the need to source multiple connector types for a project.
• Eliminates web stiffener requirements - the full-height joist flange captures the joist top chord and prevents rotation, cutting out an extra installation step and the associated material cost.
• Built for engineered wood framing - while compatible with solid sawn lumber, this hanger is specifically designed to achieve higher load values with engineered wood products, making it well-matched to modern framing assemblies that rely on LVL, I-joists, and similar members.
• Corrosion-resistant for long-term reliability - the G90 galvanized coating goes beyond basic protection, supporting durability in moisture-prone framing environments where connector longevity is critical.
