Tunnel Extenders can be used to create a longer tunnel for SureFlap Cat Flaps or the SureFlap Pet Door when they are installed in a wall.

Sureflap Tunnel Extenders from Sure Petcare fit snugly onto the tunnels of SureFlap microchip cat flaps and pet doors. You can use these accessories to create a longer tunnel entrance, for example if you need to install your Sureflap cat flap in a thicker outside wall. Multiple extenders can be stacked together to form a tunnel of any length, making even the trickiest installation a lot more simple to achieve. The Cat Flap tunnel extenders are compatible with the SureFlap Microchip Cat Flap and the SureFlap Dual Scan cat flap, whilst the Pet Door tunnel extenders are compatible with the SureFlap pet door. You can find detailed installation instructions for the Sureflap Tunnel Extender in the relevant product user manual.

Important: Please check the the manual for instructions and details of your SureFlap product before ordering to ensure you have the correct Sureflap Tunnel Extender products
