The GT300/8300 Overhead Concealed System is a heavy-duty solution that can handle busy pedestrian traffic. Its proven mechanical design delivers smooth, long-lasting operation and a flush swing arm provides a clean appearance. The door is supported by heavy-duty pivots on the top and bottom of the doorframe instead of on the operator shaft, ?which allows for convenient servicing without removing the door.
