The Door Must Be Kept Closed 5067 Sign should be displayed prominently in order to ensure that a door is never left open. This may be because the door in question is a fire door. The sign will make sure that this instruction is respected and as it is AAA photoluminescent, it will even glow in the dark if there is a lack of lighting.

To make sure that people keep a door closed, this sign will be highly visible and difficult to ignore.

Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
