Maximum Security
Bar Grille

Security grilles reduce unwanted access to ductwork in spaces where supervision is minimal and vandalism or misuse is a risk. They provide additional security in openings between secure and non-secure areas, and should be placed in every opening through a secure wall. Ideal for maximum security applications, security bar grilles feature all-welded construction and are mounted to the wall using a welded frame with optional mounting flanges.
