T-Top bollards are designed to provide increased stability in high speed traffic or windy locations. This is achieved through their wide 6kg base, which provides a sturdy foundation for the bollard. The bollards are made from moulded polyethylene, which is a durable and weather-resistant material. The polyethylene construction also makes the bollards lightweight and easy to install.

In addition to their sturdy construction, the T-Top bollards are highly visible due to their fluorescent orange colour. This bright color makes the bollards easy to see, even in low light conditions. The bollards also feature standard reflective bands, which further enhance their visibility by reflecting light from car headlights or other sources.

Overall, the T-Top bollards are a reliable and effective solution for providing increased stability and visibility in high speed traffic or windy locations.
