The side spacer is a piece made of white plastic whose function is to leave a space of 25mm between the inner drawer and the hinged door so that they do not collide with each other. It is placed where the slides will be put, and they will go over it. This spacer model is compatible with Vertex, Concept and Vantage-Q drawers. Likewise, it is also recommended to use it when the drawer is inside a closet with a sliding door with loss of opening.
