Abstract
The subject of the present disclosure is a prehung door unit structure intended to close an opening, more particularly of rectangular shape, made in a stonework construction such as a wall, rising substantially vertically and separating or demarcating two spaces within a building and, more particularly, within a high-security building, including a prehung door unit made up of at least one door leaf mounted so that it can pivot and of a fixed frame intended to be fitted into said opening. Such a structure further comprises a fixed-frame pre-frame that can be mounted in the recess of the opening and constitutes a support for attaching the prehung door unit so that the prehung door unit can be fixed removably into the opening using rigid and removable connecting means.
