PetSafe Connected Tunnel Extension Dog Door, White

Whether you’re home or not, extend your pet pooch or kitty’s fun time with the PetSafe Connected Tunnel Extension for Smart Dog Door! Designed to be used if you’re installing your medium or large PetSafe Connected Smart Dog Door (sold separately) into a thick door or wall. It gives your pet pal a safe and clear path through the door—it’s a paw-fect fit. The extension adds two inches to the overall depth of the tunnel between the smart dog door and your furry friend’s destination so he can have some fun outside. You’ll love that installation is quick and easy—no tools required. Simply glue or tape it in place. Just be sure to add enough extensions (each sold separately) so that the final tunnel sticks out of the door—or wall—enough for your pet fur-iend to come and go.
