Pet Door Mounting Adapter
This isn't required for glass installations. This product can be used with the Sureflap Microchip Pet Door and the Sureflap Microchip Pet Door Connect. When mounting in the glass, this allows mounting in circular holes with a diameter of 294mm (minimum) to 320mm (maximum). The total diameter of the mounting adapter is 380mm. The Pet Door Mounting Adapter includes two parts, one for the exterior and one for the interior of your home. This Adapter is not required for wall installations, as the pet doors have internal screw holes to enable fixing to a wall.
