Standard metal registers and grilles can be used in many different residential and commercial applications. When it comes to high-risk applications, however, standard products just won't work. That's when contractors and engineers turn to manufacturers who produce security registers and grilles.
Security ventilation products are manufactured of heavier materials and welded construction and are available in minimum, medium, or maximum security configurations. Different styles are available to provide resistance to escape or vandalism, and several levels of suicide resistant grilles are also available.
