Abstract: The present invention provides a liquid drainage assembly for an automatic, roll-up door and has an attaching member connecting a drip tray to a surface proximate the door. The attaching member moves drip tray from a position where the tray is disposed under a bottom edge of the door to collect liquid flowing across the bottom edge when the door is in an open position to a position where the tray is outside the vertical plane in which the door moves to allow the door to move to a closed position. A motor moves the door in response to signals received from a controller which ensures coordinated movement of the door and the drip tray.
