The Plastic Wall Barrier is a movable blockade that is suited for long-term temporary placement such as construction zones, park or festival events, or street markets. Built with heavy-duty plastic that is weather-resistant, excellent against environmental stress, and won't crack. The best feature is the option to be filled with sand creating a heavier, more stable, and semi-permanent panel. Each panel comes with connectors so they can be linked together forming a longer wall and they stack up to four panels high for easy out-of-the-way storage when not in use. Additionally, this product comes in numerous bright colors for high visibility or muted colors to blend into its surroundings.
