An overlap stair nose is a type of trim or molding that is typically used on the edge of a stair step where the flooring material (such as hardwood or laminate) meets the edge of the step. The "overlap" refers to the fact that the stair nose overlaps the edge of the step slightly, providing a finished look and helping to protect the edge of the step from wear and tear. This type of stair nose is designed to be installed over the top of the flooring material, rather than being flush with it like some other types of stair noses. Overall, the overlap stair nose serves both a functional and an aesthetic purpose, helping to create a safe and attractive staircase. This overlap stair nose matches the laminate flooring color #3103.
