Dimensions: Doors/ Panel (self-lining thickness) - 30mm (1.25 Inches) Overall Diameter - 245mm (9.63 Inches) Cut out Diameter - 223mm (8.75 Inches) Fitting Instructions For double-glazed doors or windows, a glazier may be required. (A) Glass Doors We suggest asking a glazier to cut a hole of 8.75 inches (223mm) diameter in the desired position and install the cat flap as detailed in 3 and 4 below. Alternatively, you can replace the glass panel with a clear plastic panel and install as detailed below. Please Note - It is not possible to cut a hole in toughened glass. (B) Wooden Doors, Plastic Panels and Screens Place a 223mm template in the desired position on the outside of the door and draw around it completely. Cut out the hole by drilling a small hole and using an electric jigsaw to cut to the inside of the line. Be sure to cut the hole square to the door, especially with thicker doors. Position the cat flap frame on the outside of the panel and screw the interior cover to it using the appropriate screw/spacer combination for your panel thickness (see table below). Do not overtighten screws and cover the screwheads with the caps provided. To train your cat to use the cat flap, prop it open (e.g. with a clothes peg) at first and use food as an incentive.
