Abstract
The present disclosure includes an extendable plumb and level measuring device and associated usage method. The device can utilize interconnected members including a first, a second, and a third member. For example, the third member can be slidingly disposed within the first and second members to extend the device to a set and arbitrary length. The measuring device utilizes a spirit level or digital reader to determine when the device itself is level responsive to positioning a extendable stopper against a construction, such as a wall, door, panel, and the like. Once level, a measuring device, such as a ruler, disposed within the device can be utilized to measure the plumb of the construction. Additionally, the device can function as an extendable level to measure an arbitrary length.
