Disclosed is a corner assembly of an outer frame of a trapdoor. The corner assembly includes a corner piece, a device attached to the corner piece and screws used to fix the device to the corner piece. The corner piece has a protective partition suitable for creating a compartment that accommodates the tips of the screws and prevents the user from accidentally inserting his/her fingers inside the compartment.
Trapdoor-insert assembly having a trapdoor with a fixed frame, a movable frame disposed in the fixed frame and a panel mounted on the movable frame. At least one of the frames including at least one section having a longitudinal seat defined by a bottom wall and by two sidewalls. The two sidewalls include two projecting wings in opposite parallel position that extend for the entire length of the section. The assembly also includes an insert, which is connected to the section and has an operating portion and a coupling body with two retaining teeth that extend along opposite directions and are engaged under the two projecting wings.
