Clinch-On covers its paper faced bullnose cornerbead with a specially engineered paper using a paper-to-steel lamination process that eliminates delamination. Our 3/4″ radius paper faced nail-on 7/8″ wide flange 135º open angle bullnose cornerbead gives you a superior joint compound adhesion and maximum protection for a professionally finished corner. Our durable fiber specially engineered paper prevents balling (fuzzing) when sanding. For superior protection, Clinch-On laminates its uniquely formulated paper to the Clinch-On proprietary coated steel. Our 7/8″ flange provides you with extra liberal installation space for nailing, stapling, screwing or clinching our cornerbead to drywall. Our paper faced nail-on wide flange 7/8″ 135º open angle bullnose cornerbead with a 3/4″ radius is designed for 135º outside corners.
