The RP-DN5138BK-14 drip seals, sold as a set of 2, are designed for the DN5138BK model, part #14. They prevent water from seeping under the shower door, providing reliable protection against splashes and moisture. Made from durable plastic, these seals are resistant to wear and deformation. Installation is simple: remove the old seals, thoroughly clean the door groove, and slide each new seal along the bottom of the glass, pressing firmly to ensure a perfect watertight fit. This quick and effective replacement helps maintain a clean, dry bathroom while extending the life of your shower enclosure.
