Abstract
The present invention relates to an attachment clamp adapted to be mounted to a ceiling, such as a dry wall or acoustical tile ceiling, for structurally supporting a lighting fixture to the ceiling. The attachment clamp, which is formed of an integral resilient metal blank and a threaded adjustment member includes a foot portion adapted to be braced against the upper surface of the ceiling and a locking finger adapted to underlie the ceiling in spaced parallel relation to the foot portion, the threaded adjustment member being operable variably to space the foot and finger to clamp a thickness of ceiling between the two noted components.
