    If the hinges are one-piece, unscrew the screws that hold the door in the box with a screwdriver or a simple screwdriver.

    1. Empty box will be easy to dismantle if it is wooden. To do this, unscrew from it all the visible attachment - anchor or screws, pull the nails.

    Ways of fixing the door frame

    The metal box can be mounted in the opening in different ways:

    • Through the holes in the profile box
    • Using mounting plates

    Fastening through the holes in the box profile

    Installation rules for entry doors allow the box to be fastened in the first way only if the thickness of the opening is more than 15 centimeters, otherwise it is easy to pry the door out of the wall along with the box. In addition, when attaching the box through the mounting holes made in it, it is necessary to embed the entrance door inside the opening.

    The fact is that if you install the box flush with the outer wall, the mounting holes will be only 4-5 cm from the wall surface, and the mount will be very unreliable. And if the wall is a monolithic concrete panel, then there is a risk when drilling holes for fasteners to stumble upon metal reinforcement, which is located in the panels at about the same depth.

    Usually the holes are provided by manufacturers immediately, and complete with an entrance door are special long anchor bolts for fastening and decorative plugs in the color of the box.

    If there are no such holes, they should be drilled at a distance of about 30 cm from each other. Subsequently, trimming fittings or steel rods with a length of at least 15 cm and a thickness of 12-15 mm, which are welded to the profile from the inside, are hammered through them into the slope of the doorway.

    For reference. If for some reason the application of welding is impossible, the metal rods after the installation of the box can be riveted by striking a sledge hammer or a heavy hammer. In this case, you need to act carefully so as not to damage the box.

    With this method of mounting on each side of the rack box should remain technological gaps 10-15 mm wide.

    Fastening with mounting plates

    The second mounting method is more common and reliable. If you know how to install a metal entrance door correctly, then you will look for doors whose box is equipped with mounting plates with ready-made mounting holes.

    At each rack must be at least three. These plates allow you to install the door in the same plane with the outer wall, as they are facing the inside of the apartment and attached to the opening at a sufficient distance from the wall surface.

    Such boxes are fixed to the walls in the same way as in the first case - with anchor bolts or steel rods, followed by welding. But the size of the technological gaps increase to 15-20 mm.

    Council To provide even more reliable fastening, it is possible to combine both methods, using both mounting plates and openings in the box.
