Swing Microchip Large is an electronic cat flap for large cats and small dogs and it is reliable, easy to use and simple to programme. The cat flap has an innovative electronic system that only allows your pet to go through it, thus preventing undesired guests from entering. In fact, Swing Microchip Large has a special antenna that detects and decodes the microchip beneath the skin of your cat or dog, unblocking it and allowing it to open. Swing Microchip Large can memorize up to 30 different 15-digit microchip codes (ISO11784) and comes complete with a Wind Stopper System for protection against draughts. The cat flap has a useful anti-shock mechanism that allows the flap to close without banging. The special lock with a 4-way regulator allows you to decide whether or not to allow your pet to enter and exit freely, enter only, exit only, or you can block the flap completely. If you need to, you can also disable the system that recognises your pet and allow the flap to function in the traditional, manual way. Memorizing the microchip code is quick and simple: all you need to do is place your furry friend near the special button on the control panel. Swing Microchip Large is made of strong plastic and can be installed in various structures and materials: wood, glass or masonry walls.
