Product Description
The Simpson BA4.28/9.5 is a top-flange joist hanger engineered for reliable performance with both engineered wood products and solid sawn lumber. Part of Simpson's cost-effective BA series, this hanger is designed to carry medium loads with solid sawn lumber and higher loads with engineered wood applications. Its full-height joist flange and two-level embossed top flange deliver superior stiffness and rotational control, making it a versatile and dependable choice for structural framing projects requiring support of double 2-1/4 in. x 9-1/2 in. members.
Features
- The two-level embossment at the top flange provides increased stiffness
- The full-height joist flange captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners
- Minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads
- Available for special order to accommodate sloped and/or skewed members
- Actual joist size: Double 2-1/4 in. x 9-1/2 in.
- Made from 12-gauge steel
- Galvanized (G90) for extra corrosion resistance
