The Premier™ Aluminum Bi-Fold Door now includes, as a standard feature, the Ascent AC-Drive and three button control box.

The variable speed Ascent AC-Drive provides for a very smooth, soft start and stop, minimizing wear on the motor and components, while significantly decreasing the opening and closing time of the door.

Initially, the door operates slowly, but once it reaches a certain height, it smoothly accelerates. When the door is at the top of its stroke, however, the door slows down and softly stops.

• Very smooth start and stop

• Variable speed

• Significantly decreases opening and closing time

• Protects your investment by extending component life
