May 15, 20205 yr Lots grade 3 is designed as a product standard but it's mainly part of a system standard. While a grade 3 product is better than a grade 2 product there is little between them. Yes a grade 3 product is better than a grade 2 but the system design is more important than just product choice based on grade. There is grade 3 compliant equipment I would never use on a. Install. Does that help?
