Abstract

A suspended ceiling is installed in position by the use of a special nail construction. The nail has a pivotally mounted end which will maintain its straight configuration when it is being driven into a solid ceiling material. Should the nail be driven into a hollow ceiling material, the end of the nail will be permitted to pivot within the hollow area and the end of the nail then functions as a retainer to hold the nail in position in the ceiling material so that the suspended ceiling may be suspended from the retained nail.
