Common questions
Will it also do inside corners?
No. The fold opens the wrong way. Inside corners need the 09410, 09411 or 05560.
Does it replace corner bead?
No. Bead goes on first. This tool finishes the corner joint.
What about bullnose corners?
Not covered. It is made for 90 degree corners.
Does it leave marks?
Two thin ridges at the wing edges. Slice them off dry and feather with knives.
