The No Admittance 8115 sign will make it clear that people are not entitled to enter a specific area. The sign uses the symbol of a hand stopping them from entry at the top and the written words are below.
This sign will be essential for you if you need to prevent people from accessing certain areas. This maybe for their own security and safety, for example. It will glow in the dark too, as it is Jalite AAA photoluminescent.
Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
