One of the primary advantages of door closers is their ability to enhance security. By automatically closing doors after each use, door closers help prevent unauthorized access to restricted areas. This is particularly important in commercial settings where sensitive information or valuable assets need to be protected. Additionally, door closers can also prevent the entry of intruders, as they ensure that doors are securely closed at all times. This feature is especially crucial in high-traffic areas where manual door closing may be overlooked or forgotten.
