Sureflap Cat Flap Tunnel Extender

Cat Flap Tunnel Extenders can be used to create a longer approach tunnel to the SureFlap Microchip Cat Flap or the DualScan Microchip Cat Flap when it is installed in a wall.
Available in white or brown to match your cat flap.
The Cat Flap Tunnel Extender fits snugly onto the tunnel of the microchip cat flaps and multiple extenders can be stacked together to form a tunnel of any length.
The tunnel of Sureflap’s microchip cat flaps are 70mm (2.75″) long and each tunnel extender adds 50mm (2″) to the length of the cat flap’s tunnel. Click on the link below to calculate the number of cat flap tunnel extenders you require to fit the depth of your wall.
