ABSTRACT:
On a beam which constitutes the body of the sheet material holding device, are slidingly mounted, by means of prismatic coupling with wings of the beam profile, one or more hook brackets for hanging the beam to mounting bars which are disposed in suspension filing systems and, respectively, at least two material holding forks by prismatic coupling with wings opposite to the wings with respect to the core of the beam profile. Locking means consisting of a screw, apt to lock the hook bracket to the beam, are on each bracket, and retaining means, generally by friction, are provided between each holding fork and he beam, to prevent the forks from indesirably moving under the effect of the weight of the bound sheet materials.
