The RP-FL33BK flange is designed to provide a watertight and secure connection for SH-CL-139BK, 800BK, ST-06239BK, and ST-07239BK shower models (part #33 or #30). Made of moisture-resistant, durable material, it prevents leaks and ensures all shower components stay firmly in place. Installation is simple: turn off the water supply, remove the old flange, and position the new one over the designated fitting, aligning the screw holes carefully. Tighten securely to guarantee proper sealing. With its sleek black finish, this flange blends seamlessly into any shower design, delivering long-lasting protection and requiring minimal maintenance.
