Designed with a built-in flexible strip for straight and uniform spacing around window and door frames or any other point where stucco meets a dissimilar material (e.g., soffits, fascia board, etc.) This flexible spacing strip is lined with a bond breaking tape that allows for two-sided adhesion, which eliminates the need for a separate backer rod. (U.S. Patent No. 7,874,123)
