Install that Petsafe pet door in walls thick and thin with this tunnel extension from Petsafe. Install Petsafe cat flaps through thicker walls with this handy tunnel extension. The extension is designed for Staywell 300, 400 and 500 series cat flaps, adding an extra 1-7/8 inches for easy installation flush with the finish material on deeper interior walls. Two extensions are required for flush installation of exterior walls with sheathing and siding. Connect several together for even thicker applications.
