Overhead Concealed Operator

GT300 & GT8300 / Automatic

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.

Our literature section includes technical resources on our overhead concealed automatic operator for you to understand its mechanics better. To ensure your automatic operators’ performance, review our technical references, technical bulletins, product manuals, architectural drawings, and more.
