Vinyl bullnose archway corner bead (VBAB) (formerly known as BCB100A) is used to provide a rounded, contemporary look to archways, curves or just about any radius. Notched flanges enable this bead to be arched to an inside or outside radius. Each tab on the archway bead should be secured with adhesive or staples before application of joint compound. Multiple perforations along the flanges enhance joint compound bond. Available in 3/4 in and 1-1/2 in radius.
