发明名称 Plumb-align device
摘要 An apparatus for conveniently plumb-aligning walls is provided. The apparatus includes an anchor for pivotally attaching the device to the ground. The anchor is attached to a support member for positioning a tubular member at a convenient height for manual manipulation. Extending upwardly from the tubular member is an extender. Attached to the end of the extender is a bracket member for clasping the top of the wall which is to be plumbed. The tubular member is equipped with a threaded rod disposed therein. The rod is received by a threaded end of the extender, so that the total length of the apparatus may be increased by rotating the tubular member in one direction, and alternatively the total length of the apparatus may be decreased by reversing the direction of the rotation of the tubular member, thereby easily and accurately plumbing the wall.
