Toe Kick is 4 1/2" in height, and 96" lengths. After installation, you'll need this to cover the front section of your base cabinets, along the floor. This gives the cabinets a nice finished look. If you're installing floor after cabinets, or needed to shim up your cabinets to make them level, you may want to add base shue to trim down to the floor. Base shue is usually used for this purpose.
