The Hawa Junior 40/Z is a top hung sliding door hardware system for use with wooden door panels. Junior 40/Z is so named because the system can support a maximum door panel weight of 88 pounds (or 40 kilograms). The “Z” in the Junior 40/Z name refers to the way the running gear attach to the door panel. “Z” indicates that the system uses suspension brackets. Suspension brackets are flat horizontal plates that screw into the top edge of the door panel. The plates then accept a short vertical rod suspended from the running gear in the track above the door.
