The general width of the mother-in-law fire door is a fire door with a size of more than 1 meter. As the name suggests, the mother-in-law type has two door leaves, one large and one small, unlike double doors. The two leaves are the same size. The ratio of the two door leaves of the double-sided fire door is usually /. The double-sided fire door generally has limited application space. When it is inconvenient to open a certain side, if the back door of some doors is equipped with a fire hydrant, the box door cannot be opened. When it is fully opened, a small door leaf is set up for easy use. You can also close the small door and only use the big one at ordinary times. If something big comes in or out, open it all.
