A plating rack for use in plating a plurality of cylindrically shaped articles such as piston rods. The articles are supported in vertical orientation between upper and lower frame structures. A plurality of individual drive assemblies each having a threaded socket are rotatably supported on the upper frame structure, and a plurality of tubular protection sleeves are supported on the lower frame structure. The upper end of each article is threaded for connection with the drive socket of one of the drive assemblies, and the lower end of each article fits within one of the protection sleeves. The drive sockets rotate in unison, and plating current is supplied to each article through its associated drive assembly via brushes which are biased against the drive assembly. The protection sleeves on the lower frame structure are hingedly mounted thereon to facilitate loading and unloading of the articles into and from the rack. The lower frame structure can be positioned with respect to the upper frame structure thereby rendering the rack suitable for articles of different lengths.
