ABSTRACT:
A file binding system according to the present invention comprises a pair of elongated rigid support members for supporting a file along its edge and securing members for securing the support members in position. The support members are fully separable from one another and from the file edge with the securing members being independent of the support members other than in the securing position, thereby adapting the arrangement for use with essentially any file size. Furthermore, each of the securing members includes securing portions for securing the support members from their outer sides along the file edge. This latter feature not only facilitates binding adjustment but also provides an extremely effective clamping of the file edge between the support members.
