Transform your Blue Line Flat Box into a quick and easy way to finish out any style of outside corner: metal, plastic or paper face bead.
Installation is quick and easy, do-it- yourself or your local tool repair specialist can get you up and running those corners in nothing flat. Just drop one side of the box over the crown of the corner and the Blue Edge will keep you running right down the bead providing a full smooth fill.
