    Abstract: The frame for hanging files may be quickly assembled and does not require tools or any type fastening devices. The rails for holding the files are positioned within the channel of a rail housing, that is positioned at the top end of rail supports. A locking bar with a cam head pivots within the rail housing to first bear against the rail and then to hold the rail in position within the channel of the rail housing. Support bars are then used to hold the locking bar in position and to provide stability for the frame.
