The Ferplast Swing 9 is a robust and reliable pet flap, designed to facilitate the entry and exit of large cats and small dogs. It stands out for its universal installation, as it can be mounted on doors and walls made of any material, including wood, glass, metal, and masonry. Equipped with a 4-way locking system, it allows you to manage your pets' access flexibly, and its anti-shock system with a spring damper ensures safe and gentle use. It also includes a cut-out tunnel for adaptation to thicker doors.
