DETAILED DESCRIPTION

(14) In accordance with some embodiments, a cover of an inspection chamber 1 is in its basic design formed with a flat door 2 which is produced from a magnetically conductive material, by way of non-limiting example a zinc-coated varnished metal sheet which is on its outer surface procured with a non-illustrated foil and a set of shaped fixtures 3. The fixtures 3 are formed from a flat bar and, in some embodiments, are either substantially L letter shaped as it is illustrated in FIG. 2A, or substantially U letter shaped as it is evident from the FIG. 3A, and are procured on their face surface of a front arm 31 with magnets 4 (which, in some embodiments, are substantially flat), and which (in some embodiments) are on this surface fixed, and in some embodiments glued. In accordance with some embodiments, side arms 32 of the fixtures 3 are formed in the way for their length not to be substantially bigger than is the thickness of the wall 5 of the materialfor instance brickwork or plasterboard where the chamber 1 is formed. In some instances in which the thickness of the wall 5 is standardised, for example in plasterboard blocks, the fixtures 3 are formed in the U shape in the way that the length of the side arm 32 between the front arm 31 and the back arm 33 is substantially equal to a thickness of the wall 5. In accordance with some embodiments, the door 2 is procured along its whole perimeter with a welt 21, which is either made perpendicularly to its front surface 22 or sloped, including, without limitation, 45 anglewise, or the welt 21 is formed rounded as it is evident from the details of the FIGS. 1B-1D. In some embodiments, the welt 21 is formed in the way that the distance of the back wall 23 of the door 2 form its peripheral edge 24 substantially equals a sum of heights of the flat bar of the front arm 31 of the fixture 3 and the flat magnet 4.

(15) In some embodiments, during assembly of the cover, the fixtures 3 are fixed, for example glued, screwed, or otherwise connected, along the perimeter of the chamber 1 which is formed in the wall 5, then the chamber is covered with the door 2, which is by its back wall 23 fixed to the magnets 4 of the fixtures 3.

(16) In accordance with some embodiments, the described cover can be designed in any other suitable manner besides those illustrated in FIGS. 1-3. Indeed, depending on the size of the chamber 1 and any other need, the cover's walls 5 can comprise any suitable amount of the fixtures 3. In some embodiments, the cover 1 comprises at least two fixtures. Additionally, in some embodiments, the chamber 1 is circular and can be covered with the circular door 2, as it is illustrated in FIG. 4, or in accordance with some other embodiments, an example of which is illustrated FIG. 5, the square chamber 1 can be covered with the circular door 2. In still another non-limiting example, the circular chamber 1 comprises a square door 2, an embodiment of which is illustrated in FIG. 6.
