Unfortunately this dog grid is not suitable for me. The processing is deficient and 2 of 4 of the screws do not even survive the first tightening with the screwdriver. Security can be no question here. Worse still is that the rubber parts and the grid evaporate any chemicals that stink so they are unsuitable for use in a car. Even after 2 weeks airing on the balcony the smell was unbearable.
