Abstract
A card file of compact and efficient design which is fitted with a compact rotary base and separate stabilizers fastened to the bottom surface of the card file. A swivel base and stabilizers attached to the file housing provide a low profile, lighweight and efficient means by which the card file can be swivelled to any desired position in the horizontal plane. Adjusting means are also available to ensure that the stabilizing means can accommodate any irregularities in the bottom surface of the file or other object to which the swivel is attached in order to provide a proper disposition of the stabilizing elements.
