Car blocking balls, also known as car blocking stone balls, stone balls, car blocking stones, etc., can be placed near pedestrian crossings or park squares to effectively restrict vehicles from entering. Car blocking balls often appear in parking lots, parks, and scenic roads. Car blocking balls are a convenient and practical space divider stone ball. The current design of car blocking balls generally has a spherical shape on the top and a circular trailer under the ball, which is both beautiful and convenient to use. They can be stabilized on the ground without cement and easy to adjust and move.
