Airfoil airtight electric box single gange case
Case of 40 electric boxes. All AIRFOIL® products use the same sealing chamber and knockout system to create a visible, airtight seal around electrical wires, cables, and phone lines that effectively prevents the infiltration of air and moisture. Each design has a 1 1/8 inch flange around its perimeter, making it very easy to establish the seal between box and drywall.
