OBS

Ces gorges constituent la partie la plus importante d'un cylindre à gorges à levier. Elles sont généralement en bronze. Leur longueur et leur angle de pénétration varient. Les pistons, aussi appelés demi-goupilles inférieures, sont coniques à une extrémité afin de correspondre à la forme de la clé. C'est le règlement de ces pistons à différentes longueurs et selon différents angles qui détermine la combinaison d'un cylindre.
