The PRIME LINE PRODUCTS M 6111 is a clear acrylic bottom guide designed for frameless glass shower and tub enclosure doors. It mounts at the base of the door panel using a glue-in installation method, keeping hanging glass panels properly aligned within their bottom tracks. The channel opening measures 9/16 inches wide, accommodating glass panels up to 1/2 inch thick. Each package contains 6 guides. This type of hardware is typically installed by glaziers, tile contractors, or experienced plumbers during shower enclosure assembly or replacement service.
These bottom guides are suited for residential tub and shower door applications where frameless glass panels require a fixed alignment point at floor or threshold level. They are used by Sterling and a variety of tub and shower door manufacturers, making them a practical replacement or new-installation option across a broad range of enclosure styles. The clear acrylic finish blends with standard frameless glass door aesthetics without adding visual bulk to the installation.
Used by Sterling and a variety of tub and shower door manufacturers. Suitable for frameless glass panels up to 1/2 inch thick in bottom-mount track applications.
Installation is performed by applying adhesive inside the guide channel and pressing it into the bottom track position at the threshold or floor of the enclosure. Ensure the mounting surface is clean, dry, and free of soap residue or silicone before bonding. Allow adequate cure time per the adhesive manufacturer instructions before loading the glass panel into the guide. No special tools are required, but verify glass panel thickness does not exceed 1/2 inch before installation.
