ABSTRACT:
A dial for a combination lock extends through a disc mounted on the housing for supporting the dial. A pair of interchangeable members, one being used at a time, are used in conjunction with the dial. The first interchangeable member is a spacer mounted on the disc between the dial and the disc for spacing the dial from the disc and covering a portion of the disc. The second interchangeable member is a cover mounted over the disc. The cover has a window through which the dial can be seen. The window includes a lens with thin plates therein for directing light from the dial in a certain path so that the dial can only be seen from one position. The cover has members for securing the lens in the window so that it is not easily removed therefrom.
