General warning sign - LARGE

Sufficient space above the logo to add a phone number if you want to.  This sign is hard to miss - it will remove the excuse that people did not know that they needed to be authorised.

The aluminium can handle direct drilling with a screw to the substance behind and is more tolerant of wind and rain.

Some differences in the colour of sign are due to the cameras taking them and the monitors of thse viewing them.
