A frame for supporting a multiplicity of files that have reenforced top edges formed with extensions intended to engage a pair of horizontal side rails and that have a web extending between the edges and hanging downwardly there between comprises a pair of horizontal side rails engageable by the extensions. Each side rail is formed with at least one aperture extending therethrough near each end thereof. A pair of end supports each comprising a horizontal cross bar and a pair of vertical legs is provided, the legs and cross bar of each end support having generally the shape of an inverted U. Each leg is formed on the side thereof opposite the other leg of the same end support and near the top thereof with a recess and a threaded bore. Each bore communicates at one end with one of the recesses and at the other end with the side of the leg facing the other leg of the same end support. Four threaded bolts are provided, each having a threaded shank passing through an aperture in the side rail and one of the threaded bores. Each aperture in the side rail has a diameter greater than that of the shank, and the shank is threaded into the bore. Each recess is formed to engage a side rail adjacent top and bottom edges thereof and to be otherwise spaced apart therefrom.
