Circle R EdgeFlex fenders are strong enough serve their purpose but flexible enough to handle wear and tear.

Circle R pioneered the bolt on rubber edge fender in the Side Dump marketplace. 

EdgeFlex fenders have a flexible rubber edge that doesn’t crack when the loader hits it. 

This feature saves on maintenance, by resisting damage to the fenders. The bolt-on fenders also reduce replacement time should damage occur due to the loader encountering the steel center. If damage occurs, the fender can be easily detached from the frame and a new one bolted on. 

Steel fenders can damage the tires of the loader and are more prone to damage themselves.

Circle R EdgeFlex fenders are strong enough serve their purpose (preventing mud and rocks from flying up and hitting the trailer and other vehicles), but flexible enough to handle being hit by the loader.
