An inspection hatch has an inner door (11), which extends inside an outer framework (2) with a quadrilateral shape, is movable, relative to the outer framework (2), between an opening position and a closing position to open and close the inspection hatch, and is provided with an outer frame (12) and with an inner closing panel; the outer framework (2) and the outer frame (12) being each defined by at least two respective support section bars (7, 18), which are coupled to one another in a sliding manner, so as to selectively control the size of the outer framework (2) and of the outer frame (12) in at least one direction (4, 6).
