New Product Announcement:
“Z” Passageway Grilles and Diffusers

August 20, 2021

KEES is excited to announce our new “Z” passageway grilles and diffusers. These products provide additional security and risk resistance for behavioral health and correctional facilities. The more complex passageways created by the “Z” shaped louvers reduce the risk of occupants looping material around or through the openings of the grille or diffuser.

The addition of these products demonstrates our continued efforts to meet the diverse needs of behavioral health and correctional facilities. Over the years, KEES has become an industry leading provider of security grilles and diffusers by recognizing that one size does not fit all. Our products can meet any security and risk resistance/anti-ligature requirement and they can be placed in any location within the facility regardless of the mounting or material requirements. As needs continue to evolve, trust KEES to provide the right product for any situation.
