The SureFlap Pet Door Tunnel Extender can be used to create a longer approach to the SureFlap Microchip Pet Door when installed into a wall.

The Tunnel Extender fits snugly onto the tunnel of the cat flaps and multiple extenders can be stacked together to form a tunnel of any length.

The tunnel of the SureFlap Microchip Pet Door is 70mm long and each tunnel adds 50mm to the length of the pet door’s tunnel.
