The Simpson BA1.81/7.25 BA Top-Flange Joist Hanger from Simpson is a cost-effective framing connector designed for 1-3/4 in. x 7-1/4 in. engineered wood and solid sawn lumber members. Built to carry medium loads with solid sawn lumber and higher loads with engineered wood products, this top-flange hanger gives framers and structural designers a reliable, versatile solution for a wide range of floor and roof framing applications. Min./max. nailing options add further flexibility, allowing the same hanger to meet varying load demands without switching hardware.

Key Features

• Two-level embossment at the top flange - provides increased stiffness, giving the hanger greater structural rigidity where it matters most and reducing flex under load.
• Full-height joist flange design - captures the top chord of the joist to prevent rotation and eliminate 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, so one hanger handles a broader range of structural requirements without swapping components.
• Available for special order to accommodate sloped and/or skewed members - makes the BA series adaptable to complex framing geometry where standard-orientation hangers cannot be used.
• 14-gauge steel construction - delivers a solid strength-to-weight ratio suited to medium and higher load joist hanger applications in both residential and light commercial framing.
• Zinc galvanized G90 finish - provides extra corrosion resistance, helping the hanger maintain structural integrity in moisture-prone framing environments over the long term.

Why This Product

• Engineered wood and solid sawn lumber compatibility - the BA series is purpose-built to perform with both material types, making it a practical single-SKU choice for mixed framing projects where lumber species or product type may vary.
• No web stiffeners required - the full-height joist flange eliminates a common extra step in joist hanger installation, reducing labor time and the need for additional blocking or reinforcement materials.
• Flexible load capacity through nailing pattern - the ability to dial load capacity up or down simply by adjusting the nailing pattern means this hanger adapts to the job rather than requiring a different product for each load condition.
• Domestic manufacturing and G90 galvanized finish - the combination of 14-gauge steel and a G90 zinc galvanized coating means builders get a corrosion-resistant, structurally sound connector that is built to last in demanding framing conditions.
