The tapered cone shape adds a little elegance to any high-traffic area like business districts, municipal parks, or downtown shopping centers. The 18" round base tapers to 9" round flat top giving it an elongated appearance. This design draws attention upward and puts eyes on their surroundings which is ideal for shopping areas, town squares, or downtown streets where the traffic is high and needs to be guided. This bollard is made with commercial concrete reinforced with steel rebars for strength and durability. We recommend anchoring onto concrete slabs or sturdy decking to prevent sinkage from the weight. In addition to being made within the USA, this product is also backed by a 2-year commercial warranty.
