How it works. The mount screws to the wall beside the door (two countersunk holes; strips work too). Each flag's hub drops onto its pin from above and swings: flat against the wall means nothing, swung out square to the wall means what it says. A bump on the shelf and a notch under the hub click it flat or out, so a draught doesn't move it. The word is raised on both faces, so it reads walking either way down the hall. Two, three or four flags; the mount prints standing in one piece, the flags flat.
What to say. READY / WITH DR / CLEAN is the classic set; NURSE, LAB, X-RAY, VITALS, a provider's initials - whatever your rooms need. Order one mount per door; the room number is on it.
