Inside Corner Rollers embed tape before wiping excess mud with a Finisher – a necessity to creating a professionally finished angle with a crisp, clean 90° finish. The one-piece aluminum chassis is powder-coat finished to make the Roller easy to clean, and long lasting. Using a Corner Roller helps by aligning tape, reducing air bubbles under paper tape, and saving you tool wear on any Corner Finisher that follows. Each roller head fits both our fixed length and extendable handles.
