ABSTRACT:
An apparatus for removably attaching a leveling device to an object. One application of the invention is attaching a carpenter's level to a substantially vertical stud at a construction site while the stud is being fastened into place. An elongated arm having a rectangular cross section is fastened to the leveling device so that it can swing between a storage position parallel to the measuring edge of the leveling device and a working position which is at least somewhat perpendicular to the measuring edge. A gripping member is provided to grip the object so that the object is gripped between the gripping member and the measuring edge of the leveling device. An aperture having a shape and a size slightly larger than the shape and size of the arm is provided in the gripping member and the arm is placed therethrough. When the gripping member is oriented substantially other than perpendicular to the arm, the inside dimensions of the aperture in the gripping member engage the arm and the gripping member is held in place thereon. The present invention allows a leveling device to be quickly and easily attachd to a vertical object, such as a stud, allowing a worker two free hands for fastening the stud into place. When the task is completed, the worker can readily remove the leveling device. The device can also be used on objects that are oriented in nonvertical positions and objects other than studs.
