Prime Line Products M 6258 Shower Door Bottom Seal

Product Description

The PRIME LINE PRODUCTS M 6258 is a clear vinyl bottom seal designed for frameless shower doors. It measures 36 inches in length and 3/8 inches in width, providing a low-profile barrier that helps reduce water leakage at the base of the door. The seal strip is constructed of flexible vinyl, allowing it to conform to the bottom edge of the door panel and maintain contact with the shower floor or threshold. This is a direct-replacement-style component installed by plumbers, tile and bath contractors, or experienced DIYers performing shower enclosure maintenance or repair.

This bottom seal is suited for residential frameless shower door applications where the existing seal has worn, cracked, or torn. Frameless shower enclosures rely on these seals to manage water containment without a metal threshold frame, making seal condition critical to preventing floor water damage. The 3/8-inch profile fits door panel edges of that gauge, and the clear finish blends with glass without visible hardware. The package contains 4 units per card, making it practical for multi-door jobs or stocking a service van.

Installation Notes

Installation does not require specialized tools, but the door panel should be cleaned and dried thoroughly before fitting the seal to ensure proper adhesion and seating. Shut off water supply to the shower and allow the enclosure to dry completely before beginning replacement. Follow the shower door manufacturer's instructions for seal attachment method, as some designs use adhesive backing while others rely on a friction channel fit. Plumbers and bath contractors typically handle this replacement as part of routine shower enclosure service.
