Plastic folding bracket is a kind of temporary road sign. Unlike metal road signs, the product is made of HDPE and does not rust，very suitable for road use. Although light in weight, the unfolded angle is perfect aerodynamic design, which gives a strong resistance to wind and a firm grip. The clever leg mechanism shortens the deployment time and ensures the rapid deployment of the deployment personnel. There is also a buckle where the aluminum plate is placed, which can quickly replace and fix the reflective sign.
