Glass Doors 

Warning: Cutting holes in glass can be both hazardous and costly if not carried out by a professional. In order to avoid costly repairs or injury we suggest that you contact your local glazier or cat door installer.
Please note: you must not try to cut a hole in either toughened glass or double glazed glass. For these types of glass the hole must be cut prior to manufacture. Fitting to Glass: No screw holes are required in the glass as the screws are connected to both the external and internal sections within the glass cut out area.
