Starting with a 14" base and tapering up to a pleasing rounded cap, this traffic bollard is 48" high and made of polyethylene plastic. Strong, weather proof and versatile, this post style bollard can be filled with water or sand for added weight and stability, then uncapped and emptied when you need to move the bollard. The integrated cap snaps onto the tapered column which can also be used for chain storage. Cap has chain pass-through opening to allow the creation of barrier lines using additional posts. Non-marking plastic won't damage vehicles it comes in contact with. Grommets recessed into the base allow permanent installation.
