How to Identify a Winchester Door or Window

Your paperwork has the information needed to identify product information. In the event you cannot locate your window/door paperwork you can locate your product order # by looking in the header or master frame of your windows.  Unlock your window and look directly up into the master frame, you will find a sticker approximately 3” long with your product information on it. You will need the “ORDER NO.” field to complete your warranty validation.
