Structure: single piece made from plastics, specifically polypropylene, manufactured by means of injection- moulding. Composed of a base with two lugs and two bars (flanges), one with five holes and another with two projections for closure. On both bars there are plastic- weakening cuts at every 5 mm. Functioning: The respective support is fixed to the file or to the filing system by means of the two lugs using a heat-bonding process. The flexibility afforded by the cuts in the bars will make it possible to use the support for different book spines. Closure of the support is achieved by means of the holes and of the two projections that exist on the bars. <IMAGE>
