Protect Swimming Pool Wall: Pool ladder bumper protector securely attaches to the end of the pool ladder to prevent the metal ladder rails from scratching the pool vinyl liner or concrete pool walls. It also helps prevent water and debris from entering the ladder tubing, reducing the risk of corrosion. Easy to Use: Simply insert the bumper into the end of the ladder pipe. The extended base at the bottom of the rubber step cap is thick and wide, providing effective wall protection and allowing for easy removal when needed.
