Speed Bumps Made from 100 percent recycled materials, these speed bumps never need paint and will not chip or split. They install in minutes. Plastic Car Stops No paint or repair is needed, because the color is molded directly into the plastic. Ten times lighter than conventional concrete blocks, and just as effective. Custom Graphics A surface-mounted sign unit and car stop can be combined to clearly identify a reserved parking stall. High-quality graphics are manufactured in our own facility. Parking Control A wide variety of surface-mounted signs, guard post covers, and and other products is available for all your parking area needs.
