The Simpson BA5.12/28 Top-Flange Joist Hanger from Simpson is a cost-effective structural connector designed for double 2-1/2 in. x 28 in. engineered wood and solid sawn lumber applications. Built from 12-gauge steel with a G90 zinc galvanized finish, this top-flange hanger delivers reliable medium load performance with solid sawn lumber and higher load capacity with engineered wood products - making it a versatile choice for residential and commercial framing projects where dependable joist support is critical.

Key Features

• Two-level embossment at the top flange - provides increased stiffness, improving structural rigidity under load and reducing flex at the connection point
• Full-height joist flange design - captures the top chord of the joist to prevent rotation and eliminates the need for web stiffeners, saving installation time and reducing material costs
• Min./max. nailing options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, giving engineers and contractors the design flexibility to match nailing patterns to specific load requirements
• Compatible with engineered wood and solid sawn lumber - supports a broad range of framing applications without requiring separate hanger models for different member types
• Available for special order to accommodate sloped and/or skewed members - allows the hanger to be adapted for non-standard framing conditions where standard square cuts are not possible
• 12-gauge steel construction - delivers the strength and durability needed to handle medium-to-high structural loads in demanding framing environments
• G90 zinc galvanized finish - provides extra corrosion resistance, extending the service life of the connection in moisture-prone or treated-lumber environments

Why This Product

• One hanger, two performance levels - the min./max. nailing design means a single hanger model can serve both moderate and higher load applications, reducing the number of SKUs a contractor needs to stock and simplifying job-site management
• No web stiffeners required - the full-height joist flange captures the top chord and prevents rotation without additional hardware, cutting installation steps and keeping labor costs down on large framing projects
• Built for engineered wood performance - while the BA series handles solid sawn lumber at medium loads, it is specifically engineered to carry higher loads with engineered wood products, making it a strong fit for modern floor and roof framing systems that rely on LVL or I-joist members
• Corrosion-resistant from the factory - the G90 galvanized coating delivers extra protection against rust and degradation, making this hanger a dependable long-term choice in humid, exterior-adjacent, or pressure-treated lumber applications
