The illustrated structure provides a locking mechanism for holding a series of spaced, axially aligned disks in place during spin drying following a process operation such as plating. The mechanism shown in the figure locks the disks in place by use of a cam action roller made of solid rubber. The disks are retained by a roller 1 and a pair of fluorine resin rods 2 which are mounted on a hub 3 and engage the inner diameter of the disks. The rods 2 are carried in grooves 5 and the camming roller 1 is retained by a series of plates 6 which hold the reduced diameter portions 7 in grooves 8. Roller 1 also is secured to a ring 3 which, when aligned with hub 4, causes the eccentrically mounted, increased diameter portions 10 to project and engage the disk inner diameters.
