The 4-way manual cat flap from Ferplast is a pet door devoted exclusively to your four-legged friend. This swing flap comes with an innovative wind stopper system that 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 5cm 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.
