Can it be done?? We're talking a typical French door with exterior grids that is currently a right inswing and it needs to be a left inswing. Looking at it, it seems all that would need to be done is remove the door slabs from the hinges and turn the slabs around, un screwing the astrigal(or mull) and reattach it to the original but just on the other side. Perhaps filing down the channels the hinges set in on the slabs. The only difference would be the screw holes around the exterior grids would be on the outside instead of the inside. What does anyone think??
