<p>The equipment (4) is attached to the wall (2) by means of two metal pressings (1) which are identical but the pressing attached to the equipment (4) is inverted. Each pressing has a U shaped section (5), at one end, of width (d), and ends in a shoulder (8) leading to an area (7) parallel to the central area and then ending in a bevelled portion (6) of width (D), which is slightly less than the width (d) of the U section. The upper pressing attached to the equipment can thus fit into the lower pressing attached to the wall.</p> |
