By installing edge trim strips, manufacturers can mitigate the risk of injury. Furthermore, edge trims help guard against wear and tear, moisture ingress, and other forms of damage that could compromise the integrity of the material being protected.

The Type 2021 typically has a seal face diameter ranging from 1.5 inches to 5 inches (38 mm to 127 mm), depending on the specific application. A larger diameter generally provides a greater surface area for sealing and helps accommodate variations in alignment.
