Nornal site-boards are ideal for longer jobs but Flexi is suitable for any job. Make it the first thing out of the Van when you arrive on the job & make the last thin in the van when you leave even if you ar only going to be a few hours.
Flexi can be turned so that it is viewed straight on by passers-by and being double sided can be viwed straight on in both directions.
If you are waiting for a delivery – use it to keep a parking area clear. Want to keep access clear to the back of your van? Use to stop somebody parking too close.
