These brackets extend the mounting header to accommodate door frames or header configurations that require additional clearance or offset. The hardware is a lock accessory sold as a single unit and is typically installed by locksmiths, security technicians, or access control professionals during new installations or retrofit projects where standard mounting geometry does not align with the door opening.\u003c\/p\u003e\n\u003cp\u003eThese header extension brackets are intended for use in commercial and institutional access control installations.
