- Modular extension tunnel of 5 cm depth
- Ideal for dog and cat flaps like Swing 1,3 and 5
- Screws not included
The modular extension tunnel, which is useful for smaller dog and cat flap models like Swing 1, 3, and 5, can be ordered separately. It is helpful for mounting smaller flaps on thick structures (the flap is already provided in the tunnel for larger models). All Swing 1, 3, and 5 flaps can be used with tunnel extensions, which come in two colors. There are no screws included.
