It is used to bridge the gap between two pieces of flooring where they meet at a joint. Hardwood flooring splines are commonly used when you need to change the direction you are laying your wood floor. The change in direction can occur for various reasons, such as transitioning from one room to another, creating a design pattern, or accommodating structural features in the space.
