It is a roller tool having equal number wheels on each side of a rigid frame bent vertically on an axis to the angle desired. The tool has a wiping device attached to the top of the rigid frame that is also bent vertically along the same axis which has a wiping edge that extends past the edge of the wheels that makes contact with the wall board during use and feathers the excess joint compound after the corner bead has been set by the wheels.
