This Concave Quarter Round is a type of molding that is used in conjunction with laminate flooring. A Concave Quarter Round is a quarter-circle in cross-section, with one side designed to be installed against the vertical surface (such as a wall or baseboard) and the other side designed to cover the gap between the flooring and the wall. It's also a slightly scooped or hollowed-out molding on the side that covers the gap, which can help to create a more finished and polished look. This Concave Quarter Round matches the laminate flooring with the color #8005.
