ABSTRACT:
An adapter assembly for positioning a level on a structural component includes a mounting mechanism that attaches to the level and an arm that is pivotally mounted on the mounting mechanism. The arm supports at one end a gripping mechanism, such as a bar, that extends outwardly in parallel to the axis of rotation about which the arm pivots. A spring extends between the arm and the mounting mechanism. To attach the level to a structural component a user pivots the arm to draw the gripping bar away from the level. The user then positions the level and the gripper bar on opposite surfaces of the structural component, and releases the arm. The spring draws the arm against one surface of the structural component and holds it in position, to clamp the level to the opposing surface of the structural component. The mounting mechanism may include a pivotally mounted bracket that pivots about a second axis of rotation. The bracket pivots the arm 90.degree. relative to the surface of the level on which the arm is mounted, so that the level can be positioned in an alternative orientation against the surface of the structural component.
