SureFlap tunnel extenders can be utilised to extend the approach tunnel to the SureFlap microchip cat flap when it is installed in a wall.

The SureFlap tunnel extender fits perfectly onto the tunnel of the SureFlap microchip cat flap, and it's possible to stack numerous extenders together to create a tunnel as long as necessary.

The SureFlap microchip cat flap tunnel is 70mm in length, and every tunnel extender increases the length of the cat flap tunnel by 50mm. Available colours are white and brown.
