Opposing steel door skins are punched to provide openings of the required size for a specified lite unit. Lite unit locator and retaining flanges are simultaneously formed on the two skins. A prefabricated lite assembly consisting of a pane of glass and surrounding mitered wood frame with sealant is placed between two steel skins in interlocking engagement with the locator and retaining flanges and the door is put through a foaming operation to produce an interior foam core around the margins of the lite assembly or unit.
