An alignment device allows hinges from an old door being replaced to be transferred to a new door in the corresponding position to ensure that the new door is properly aligned in the door frame. The tool has an elongate channel that is placed next to the door in the height direction. A stopper aligns a comparable tool with a top edge of the door having its hinges removed. Brackets secure the channel to the door and ensure that the channel is parallel to the door. Once the tool is fixed relative to the door, the hinges can be attached to the channel. After the hinges are attached to the channel, they are removed from the existing door. The tool can now use to install hinges on a new door at a remote time or place from the hinges.
