One of the least expensive details in your kitchen cabinet order is the bottom trim on wall cabinets. Designers also refer to this as light rail molding. This humble strip of trim packs a powerful punch in terms of style and function.

Preventing Glare

A primary function of under cabinet light rail molding  is to conceal light fixtures mounted under wall cabinets and prevent glare. While working at the counter, the shallow light strip tucked behind the cabinet, is hidden. The light may, however, present those seated in an adjacent living room with an unsightly view and irritating glare. If the fixture is located at the front of the cabinet, an inch of trim will solve the problem.

Enhancing Your Kitchen Design

Working in combination with the cabinet crown molding, the light rail (sometimes referred to as a light skirt) will frame and complete your design. Light rail molding should complement your cabinet door style in addition to enhancing the overall effect you want to achieve. That may be a crisp, contemporary look, a traditional feel, or a graceful transition between the new kitchen and its original architectural detailing.

Light rail can be high or shallow, aligned with the cabinet or subtly projecting, and constructed from a variety of moldings. Your designer will have suggestions and will provide computer-generated images so you can see how it pulls the cabinetry together.

Allowing Space

When adding light rail to a cabinet design, be careful to preserve the height of your countertop workspace. The National Kitchen and Bath Association recommends a 16 to 18-inch space between the countertop and lower edge of the wall cabinets. Some building codes have even higher requirements, so make sure you speak with a designer or contractor before any final decisions.
