What is the purpose of a hanger rail?

A hanger rail serves the specific purpose of supporting wall cabinets, making it a critical component in both kitchen and other cabinetry installations. By providing a secure and level surface for cabinetry, the hanger rail ensures that the cabinets are installed at the correct height and can bear the weight of the cabinet contents. This installation method enhances both functionality and aesthetics, allowing for even distribution of weight, which is crucial for preventing sagging or pulling away from the wall over time.

The need for such a support mechanism comes from the nature of wall cabinets, which are often too heavy to be adequately supported by just wall anchors or screws directly into drywall. The hanger rail distributes the load more effectively across a larger area of the wall, thus enhancing the overall stability and longevity of the installation.
