Also available with an additional (standing) support mechanism to ensure filed objects are kept upright, thus preventing them from bending over if the folder is not full to capacity. For books it can also be used as a book shoe.
Products are made from the KLUG standard assortment of corrugated board types MW 1.6 and MW 1.7, ageing resistant and with guaranteed permanency in accordance with ISO 9706. The KS 9 shelf file can also be made from other material types, including solid board.
