Used for off-angles, bay windows, inside or outside 90 deg. corners, or where a definite straight inside line is required. Material can be second coated immediately. Quicker to install where framing members and drywall are straight. Saves 25% to 50% on installation time over other products. Made of high tech composite material. Installation does not require fasteners, or stapling. Drywall tape will not fuzz-up during sanding. 2-1/4" W. x 100' L.
