Maximum Headroom Sign 600mm x 200mm x 1mm thick - RA1 Reflective Aluminium.
This RA1 sign utilises retro-reflective materials that have the ability to reflect a significant proportion of emitted light back towards the light's point of origin. This means that this sign is particularly visible at night when illuminated by vehicle's headlamps.
To ensure drivers of all ages and backgrounds understand it, the sign is displayed showing the height required in both imperial and metric measurements.
Material: The sign is made from 1mm thick, hard wearing, reflective RA1 aluminium. This is easy to see, even at night, as the vehicle’s headlights will light it up as they approach.
