The Asgard® CR01-AD Inside Corner Roller attaches to the FH-AD or XH-AD Support Handle to quickly and accurately embed the joint tape into the internal corner joints. Use the Inside Corner Roller immediately after applying joint tape to the internal corner with the Automatic Taper. The CR01-AD forces excess joint compound out from behind the joint tape in preparation for the Angle Head. The Asgard CR01-AD features stainless steel rollers for crisp edges and long life.
