Water supply, sewerage and other utilities - all this in buildings cleaned the walls, floors, ceilings. However, their exploitation is often a need for inspection, repair, prevention works. To access the hidden communications used audit hatches, in particular, interior hatches.

As the name implies, floor hatches are designed to work with networks, garnished under the floor. Often interior hatches could not be masked, the simplest example - sewer manholes in the streets. In the back room, too, are often installed interior hatches of corrugated metal (aluminum, steel, brass). There is no need to hide them, on the contrary, they are often specifically stand out.

Another principle is valid in a residential area, shops, offices. Here interior hatches need to hide such a way that they did not ruin the interior and not conspicuous. It uses inflatable hatches. On the surface, their lids made deeper, which can be filled by any flooring - parquet, carpet, ceramic tile, laminate. Height of rim at the lids may be different (typically from 20 mm) that allows you to select the model most suitable for each cover.

• Filled interior hatches are increasingly being used outside the premises. Their lids shut with concrete, paving tiles, and other coatings used on the street. Load capacity of floor hatches are much greater than that of models designed for the premises. Although they both have multiple safety margin that allows to put on the floor hatches any furniture, equipment and other gravity.

Often interior hatches have gasket, which are glued lid. Luke is sealed with a seal, it protects from moisture, not only communication, but the room itself. Also, do not penetrate any dirt, dust and odors. In order to interior hatches truly watertight, check the seal quality and accuracy with which the cover is secured to the hole, it should be after it is laid on the floor and cover, and the hatch. Under these same conditions, it turns out and the final strength and load capacity of floor hatch.
