What is a Light Rail Molding?

A light rail molding is a decorative piece of trim that is installed at the bottom of wall cabinets in a kitchen or bathroom. It is typically a thin strip of wood or other material that helps to conceal the under-cabinet lighting fixtures and the electrical wiring that powers them. The light rail molding is installed flush with the bottom of the cabinet and runs along the entire length of the cabinet run.

Light rail molding can be used for both functional and aesthetic purposes. From a functional standpoint, it can help to direct the light from under-cabinet fixtures downward and onto the countertop, providing better task lighting for the work surface below. From an aesthetic standpoint, light rail molding can add a finished look to the cabinetry and help to tie together the design of the kitchen or bathroom. It can be made from a variety of materials, including wood, metal, or plastic, and is available in a range of styles and finishes to complement any décor.
