A door bushing system includes bushings formed as part of a molded resin door jamb in an insulated steel shell safe door. The mold for the door jamb is designed to form as many bushings as are required and can also form stubs or sleeves for mounting other safe components. The bushings can support parts of such components as combination locks, key locks, and door handles. The combination lock and the handle have spindles whose opposite ends have identical configurations to facilitate assembly. The spindles are also made from resinous material to reduce heat transmission and to allow attachment by insert molding. Because the bushings are installed automatically with the door jamb, this door bushing system eliminates the need for separate installation of bushings after assembly of the door, ensuring proper alignment and reducing costs.
