Featuring Gold Anodized Runners with inline wheels, these premium Corner Finishers are designed to wipe, feather, and finish both sides of any inside angle between 72° and 135° in a single pass, with little need for cleanup or sanding. Precisely adjusted feathering tabs ensure a fast, uniform finish every time, while the hardened stainless steel wiping blades, and stainless runners keep them finishing over countless angles. Their lightweight aluminum bodies connect effortlessly to Flusher Handles. The patented design of the Roller Runners reduce friction for a smoother glide along the angle; eliminating chatter, and rolling over wet flat tapes without catching.
