Abstract: A deadbolt assembly for securing co-mounted doors together and activating at least one deadbolt may include at least a first retention component and a first actuator interface mounted to or defined by a first coupling assembly of a key-side assembly operatively mounted to one of the co-mounted doors, and at least a second retention component and a second actuator interface mounted to or defined by a second coupling assembly of a lever-side assembly operatively mounted to the other of the co-mounted doors, at least one of the key-side assembly and the lever-side assembly including a deadbolt assembly having a deadbolt configured to be responsive to actuation thereof to extend a deadbolt therefrom, wherein actuation of the deadbolt assembly also causes the first and second retention components to secure the first and second coupling assemblies to one another.

Abstract: A retention assembly secures together field-coupled handle assemblies of co-mounted doors and may include a first retention component mounted to or defined by a first magnet housing of a first door handle assembly operatively mounted to one of the co-mounted doors, and a second retention component mounted to or defined by a second magnet housing of a second door handle assembly operatively mounted to the other of the co-mounted doors, the first and second magnet housings arranged such that magnets carried by each align with and magnetically couple to one another and such that the first retention component aligns with the second retention component and mechanically couple to one another as the first and second door handle assemblies are brought into contact with each other.

Abstract: A ready-to-install door system including, prior to installation, a frame including a hinge-side vertical bar attached at a top end to a horizontal bar that is further attached to a top end of a latch-side vertical bar, and a threshold portion that is attached to a bottom end of the latch-side vertical bar and a bottom end of the hinge-side vertical bar, a door rotatably attached to the hinge-side vertical bar of the frame, and at least one first removable spacer located at a first location of the door between the door and the frame, and configured to at least maintain a desired squareness of the door system prior to installation, wherein the first removable spacer is configured to be removed after the door system is installed.
