Keep clinic procedures moving smoothly by indicating the status of an exam room with these color-coded, signal flags. Set up your own color-coded signals for doctors and staff. Different-colored flags can show "doctor in exam room," "nurse and patient preparing for doctor," or "x-rays being taken." Signal flags are made of high quality, scratch-resistant plastic and plexiglas and include mounting hardware. Signal flags are held firmly in place with tensioning springs and snap to five positions.
