Swing Microchip Large is a swing door for large cats and small-sized dogs with a fantastic selective recognition system with microchip! This swing door has an antenna that detects and decodes your pet’s subcutaneous microchip, automatically unlocking every time he approaches to pass through the door. Made of sturdy plastic, this swing door comes with wind stopper, to keep air draughts out, and with a super effective 4-way closing system so you can choose how to adjust its operation: exit only, entry only, entry and exit, full lock (your pet will not be able to pass either way). This allows for controlled passage and keeps foreign dogs or cats from coming in. Reliable and easy to use, the Swing Microchip swing door runs on batteries (not included) and comes with a low-battery indicator. Very versatile, the swing door can memorize up to 30 different standard microchips (ISO 11784), unambiguous all over the world. It can be installed on any material. Note: Be careful when installing the swing door on tempered glass and double-glazed glass (the holes must be factory drilled) or on metal doors that interfere with the swing door recognition system (a wooden spacer of at least 5 cm must be placed between the metal and the swing door). The packaging includes a collar with microchip, in the event your animal doesn’t have a subcutaneous chip. It should only be used with the swing door. Choose the model to suit your pet's size.
