Phillips 3/4″ gripSTIK® MAX-Flex® bullnose archway bead is designed for maximum flexibility with our unique design allowing it to conform to almost any radius creating a round, elegant look. Each tab on the notched flange should be secured with either staples or adhesive before applying the joint compound. Flanges feature many perforations, deeply knurled mud anchors, and the entire product is specially textured which all greatly enhance paint and mud adhesion.
