• Fire opening in a ceiling construction holds the lid automatically due to gravity in the opening. Because no additional holding elements or the like are required, the fire protection opening has only a very few components, namely, in the simplest embodiment, essentially only the plate with the frame, the lid and the fire protection lid.

For rectangular openings and lids, especially if they are not square, the lid can be easily removed through the opening. Due to the rectangular, triangular or polygonal basic shape of the opening of the plate and the cover, straight sections may be provided and the straight sections of plate and / or lid may be connected by rounded sections. When using brittle materials there is an increased tendency to fracture in sharp-edged section, especially when straight section and an acute angle meet. To reduce the tendency to break, the straight sections are connected by rounded sections. These rounded sections are radiused. Advantageously, the radius is between 1cm and 10cm. Radii in this area reduce the tendency to break without reducing the opening too much.

For this it is necessary that the height of the mounting space corresponds at least to the height of the lid. Corresponds to the height of the mounting space of double lid height, the handling improves during the application of the lid. Suitable for this embodiment
