Checkpoint® is manufactured from Polyethylene. This special grade is suitable for heavy-duty applications such as high load urban duty cycle service or where full axle loading is the norm. The material used is a virgin polymer and is UV stabilised. It is therefore dimensionally stable. The polymer does not degrade in sunlight. Checkpoint® can be cleaned using any of the available vehicle cleaning agents, detergent solutions or paraffins. Checkpoint® are not attacked by road salts or petrochemicals. The pointer being large, it is highly visible even when coated with road or operational grime.
