The peculiarity of these hatches is that they have two doors for opening. In this modification of invisible hatches, it is also important that the inspection doors can have different widths and be asymmetrical.
Thanks to the unique technical design mechanisms, the hatch, when installed in the opening and further cladding, creates the effect of 100% invisibility (invisibility) of the hatch against the background of decorative finishing.
The two-door hatch is used in a wide variety of rooms and for a variety of technical tasks. Due to its design capabilities, the main use of the hatch is comfortable access to communication elements, ranging from taps, filters and meters, ending with pumps, siphons and boilers, elements that require systematic audit access, maintenance and repair.
