Door stopper with two components: a door block with an 18° inclined magnet and a ground block with a retractable plate. When the door approaches, the magnet lifts the plate, activating the block. When not in use, the plate automatically returns to a flat, recessed position, preventing obstacles. Equipped with shock and anti-vibration gaskets, and a set of 2 gaskets (2 mm and 4 mm) to adjust the ground block height as required.
