A latching system for live bolts as in a door retains the live bolts within the door until the door is closed. A latch holds a live bolt link against travel that would insert the live bolts into the door body jamb until a link lifter forces the link out if the latch against the bias of a hold-down spring. The link lifter can take the form of an inclined surface on a cam mounted on the hinge side of the door. The cam engages the door body jamb as the door closes and travels into the door until the link lifter engages and lifts the link out of the latch.

An insulated steel shell safe has a lip extending inward around an inner periphery of a door opening; and a molded resin liner, inserted into the steel shell through the door opening, is connected to the lip to form an interior of the safe. The liner has a face flange seated against the front face of the lip and outwardly extending ribs engaging a rear face of the lip. This supports the liner within the shell by engagement of the face flange and the ribs with the lip while insulation material is poured through a back wall of the shell into the space between the shell and the liner.

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.
