Product Description
The Simpson Strong-Tie BA7.12/18 is a top-flange joist hanger engineered for use with double 3-1/2 in. x 18 in. engineered wood and solid sawn lumber members. Designed as a cost-effective, one-piece alternative to welded hangers, the BA series delivers reliable performance across a range of load conditions. This hanger supports medium loads with solid sawn lumber and higher loads when paired with engineered wood products. Its full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners. The BA7.12/18 features flexibility in nailing - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing configurations to support higher load demands. Constructed from 12-gauge steel with a G90 zinc galvanized coating, this hanger is built for lasting durability and corrosion resistance.
