The Stairway Level G 4877 Sign is used to make sure that people realise the actual level they are on, within a building. Use these signs to clearly identify every floor. You may wish to place this sign on a stair well or near to a lift shaft. If people need to find a certain level, in a building, this sign provides excellent guidance. It will glow in dark places too, as it is Jalite AAA photoluminescent.
