requiring a secure access point for human entry. This is the first economical composite ring and cover unit in the United States to meet and  exceed the AASHTO Class D HS-20 Traffic Loading requirements. The Super Cover™ was able to average 130,000 total force weight before failure. That’s 90,000lbs over the requirement for Heavy Duty HS-20 rating.
