Abstract
An improved mounting bracket for a coil spring mounted poster display structure. The bracket comprises a metal plate having at least two stepped levels with a threaded hole formed through each level. The bracket is adapted to fit between adjacent coils of the spring so that the holes in the bracket are parallel to the axis of the coil spring. The coil spring is fastened to the poster display structure by a pair of mounting bolts which are positioned through corresponding holes in the structure and screwed into the holes in the bracket. The stepped levels in the bracket insure that the holes in the bracket will properly align with the holes in the display structure.
