Designed for frameless glass shower doors, this polycarbonate bottom seal provides a clear, durable closure along the bottom edge. It is intended for glass that is 3/8 in. thick, with an allowable floor gap up to 11/32 in. (9 mm). The material maintains its color and shape over time, resisting compression and deformation under regular use, so the seal stays functional after repeated opening and closing. The soft fins at the bottom are designed to glide over the threshold and help the door move smoothly without rubbing or adding noise. The seal can be trimmed with common tools to fit shorter doors, making installation versatile for different door lengths. It installs without glue by placing it under the door and pushing up from the hinge side until the edge grips the glass. Before purchasing, measure both the glass thickness and the bottom gap to confirm compatibility, as sizes and tolerances influence performance and leak prevention. The design aims to minimize leaks along the door base while remaining unobtrusive to the bathroom style, preserving a clean look without visible fasteners or bulky hardware.
