  • Elvaloy technology provides lifelong flexibility plus chemical, UV and infrared light resistance to vinyl top
  • High-visibility yellow top layer draws attention to spills

    "Our department deals with a lot of hazmat calls. These sewer covers work. They are durable and re-useable. You'll notice by the thickness and weight. These drain covers are no joke. First on scene, we deploy these right away just in case. To keep chemicals from entering the waterway. I can only imagine the amount of aquatic life we have saved using these drain covers. "
