The DoorJack ($20) is a clever foot lever for lifting and rehanging doors up to 240 pounds. The 10-inch-long device is weighted to sit nose-down so it can slide under a door more easily. Once the door is elevated (up to 1-1/2 inches), the lever can be pivoted to move it laterally onto its hinges. The tool's smooth, glass-filled nylon body is less likely than a drywall lifter or flat bar to mar door or floor surfaces. 877-399-5225, www.doorjack.com.
