Sureflap Tunnel Extender for Microchip Pet Door White

Description: Let your pal get inside safely and securely with the SureFlap Pet Door Tunnel Extender. This tunnel extender is designed to be used with the SureFlap Microchip Pet Door. Once the door has been installed in the wall, the extender fits snugly into the 7cm long tunnel of the pet door, providing your large cat or small dog with an easy-to-access tunnel that leads right up to the door flap. You can use multiple extenders to create a custom any-length tunnel depending on your wall thickness, and each extender adds an additional length of 5cms. Plus, it comes in two colors, so you can choose the one that suits your household aesthetic!
