Adams Rite 4089 130, Exit Indicator - Clear Anodized (26D)

Provides unmistakable notification to building occupants of an exit's "locked" or "open" condition. Under many local building safety codes, this allows the use, in certain occupancies of a security deadlock instead of cumbersome and insecure panic devices. It includes permanently adhesive header sign: "This Door Must Remain Unlocked During Business Hours.”
