A header is a single member composed of two or more wood members, securely attached together and used to transfer loads above openings. Headers are used to create openings for windows, doors, and interior passageways. They serve a significant structural purpose. Since windows and doors cannot support weight other than their own, the weight of above these opening must be collected and redistributed to adjacent studs. The depth of the header is determined by considering the weight from the structure above and the width of the opening.
