Inside Corner Roller NorthStar

The NorthStar Corner Roller has cast machined body, it is delrin with outer stainless steel wear rings. Delrin is one of the best bearing materials available for low speed applications. The rollers have a closed back to prevent joint compound caking between body and roller. The rollers run on hard-chromed bushings for durability. The rollers have "play" to roll a tighter corner by conforming to the walls.
