The Swing 5T 4-way manual cat flap from Ferplast is a pet door devoted exclusively to your four-legged friend. This 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. Additionally, a passage indicator will help you to understand whether your pet is indoors or out. It consists of a flag placed on the bottom of the pet flap, which will face the direction in which your furry friend last went. This pet flap comes with a partial tunnel. Simultaneously, a new modular extension tunnel is also available as an accessory which is 5 cm in depth (screws are not included). 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.
