The Haydn® Plumb Bob Carded is designed to help determine exact vertical alignment. The simple metal bulb with a point on one end uses gravity to help determine a plump vertical line. Ideal for straightening a doorway, wall, or other tall vertical structure, that is longer than a conventional level. Made from tough-wearing cast iron, it is durable and corrosion resistant — making it an inexpensive option for DIY, handyman and construction use.
