One of the most critical functions of window and door fittings is to provide security. High-quality locks, hinges, and handles are essential for safeguarding the home against intruders. Multipoint locking systems, for example, are becoming increasingly popular due to their ability to secure the door at multiple points, making it significantly more challenging for burglars to gain entry. Additionally, reinforced hinges and heavy-duty handles not only provide added security but also enhance the durability of the doors and windows, ensuring they withstand daily wear and tear.
