Flush-mounted box for housing hydraulic components comprising a frontally open box body, which is configured to be housed and fixed in a cavity made in a wall, a slide, which is telescopically coupled to the body with the possibility of sliding in a direction perpendicular to the wall, a frame, which is fixed to the slide and is provided with at least one front closing element that can be fixed to the body, and a front closing plate, which can be housed in a compartment of the frame and is designed to cooperate with stop elements of the frame and to be magnetically connected to them; the position of the slide is adjustable so as to place the front closing plate flush with the wall.

A container is described herein that is configured to be mounted between joists in a substrate of a structure, such as a floor, wall, or ceiling. The container includes a body portion sized to be disposed between the joists and a lid to cover an opening to the body. The lid can further be configured to be coplanar with a covering material of the substrate so that the container does not project outwardly from the substrate.

In accordance with some implementations, a cover of an inspection chamber is described herein. Such a cover can provide a selectively openable and closable cover for covering of openings in walls of buildings or other structures where it is necessary to assure access to air condition devices and distribution of water, gas or electricity, and/or other items. Other implementations are described herein.
