ABSTRACT:
A clamp for temporarily attaching a level to a construction component. One embodiment includes an elongated metal or plastic, inverted U-shaped body with an opening in the center of the top wall that extends down the side walls through which the level bubble is seen, a pair of pivotally-mounted, spring-loaded, opposed jaws for temporarily gripping the construction component, and a microcatch patch or screws for temporarily attaching a level to the body. A second embodiment includes a pair of bent-wire clips, where each clip has a cross piece and a downwardly extending pair of legs that are curved inward so that the ends are closer together than the length of the cross piece and the level is temporarily attached to the clips by friction between the legs and the level, and a pair of opposed bent-wire, spring-loaded jaws attached to the end of the legs for temporarily gripping the construction component.
