The Swing 15T 4-way manual cat flap from Ferplast is a pet door devoted exclusively to your four-legged friend. You can install it easily in any wooden, metal or glass door and in brick walls! This 29.7 cm by 34.5 cm pet flap will definitely be a must-have for your adventurous dog or large cat. The swing flap comes with the innovative wind stopper system, which protects against air draughts. Thanks to its 4-way locking system, it allows you to adjust the type of opening according to your needs, whether entry only, exit only, entry and exit, or closed. The flap comes with a tunnel of 5 cm, allowing it to be adapted to any structure. Please note that before installing in glass structures, we recommend you to consult a glazier, as it is not possible to drill holes in toughened safety glass or double-glazing unless they were previously created during manufacture.
