Pet Door Tunnel Extender

SureFlap pet door tunnel extenders can be used to create a longer approach tunnel to the SureFlap Microchip Pet Door when it is installed in a wall.

The Pet Door Tunnel Extender fits snugly onto the tunnel of the SureFlap Microchip Pet Door and multiple extenders can be stacked together to form a tunnel of any length.

The tunnel of the SureFlap Microchip Pet Door is 70mm (2.75") long and each tunnel extender adds 50mm (2") to the length of the pet door’s tunnel.

View the chart below to calculate the number of tunnel extenders you require to fit the depth of your wall.
