The present invention relates to a system for reinforcing door frames and doors, and in particular to a unit including twin plates which are joined one to the other transversely through the door and which are positioned on the outside and on the inside of the door to reinforce the same at the level of the handle, the latch and the dead bolt. An inner plate is also proposed which is hidden in the door frame to reinforce the same at the level of the dead bolt. The hidden plate is installed on the exterior of a new door frame and it includes as an appendix a projecting collar which extends through the door frame and which is adapted to surround the dead bolt in the door frame; the hidden plate mounted in a previously installed door frame which is provided with a weather-strip has the shape of a “S”and is installed in the groove which normally receives the weather-strip by taking up the place of a section of this weather-strip, and by also extending to the location of the striking plate at which point the plate defines also an opening which allows it to surround the dead bolt.
