I installed this motor on a one-piece tilt-up door with Franz tracked hardware. The only reason I was comfortable with this concept is the rollers are on both the top and the bottom of the track. That adds a layer of safety to the operation. I'm less concerned with the motor pushing the door off of the tracks.
The variable speed motor makes for a smooth open and close. At no point does the motor jerk the door nor does the door buck back.
Повторяем попытку...
