My company recently purchased stanchions for crowd control during emergency situations. My analysis of this product showed that it is incredibly durable and reliable in an industrial and scientific setting. The stanchions are easy to assemble and the included chain is of high quality. The STANCHIONS are also lightweight and easy to move, making them ideal for quick deployment. The only drawback is that the price is a bit higher than some other options on the market, but the quality is worth the investment. Overall, i highly recommend this crowd control equipment for emergency response situations..
