1/2-Inch Glass – 39-Inch Frameless Shower Door Bottom Seal with Drip Rail

Keep water inside the shower with this 39-inch clear bottom seal, designed specifically for 1/2-inch-thick frameless glass shower doors. The seal installs along the bottom edge of the glass and features an integrated drip rail that helps direct water back into the shower area.
