Bird-B-Gone’s Bird Net Curtains enable roll-up doors to remain open for ventilation during working hours, while reducing the opportunity for birds to enter the building. Each Curtain is custom-cut, based upon your specifications and door frame size. Three net sizes are available: 0.75-, 1.125- or 2-in. mesh, depending upon the type of bird you wish to keep out. The Curtains open and close easily to allow for in-and-out traffic. Bird Net hardware and industrial curtain track are included for easy installation.
