The Hawa Junior 120/A is a top hung sliding door hardware system for use with wooden door panels. Junior 120/A is so named because the system can support a maximum door panel weight of 264 pounds (or 120 kilograms). The “A” in the Junior 120/A name refers to the way the running gear attach to the door panel. “A” indicates that the system uses one-way 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.
