Abstract: An improved spacing and positioning device is provided for facilitating spacing and positioning of construction materials. The device allows for the installation of construction materials in various orientations. Preferably, the device is used in a set of two or more, which are placed at proximate opposed ends of the materials being spaced, to ensure correct spacing and positioning of the workpiece materials along the length thereof. The device includes a self-adhesive material on one or more surfaces to allow the spacer to be positioned on vertical or pitched construction members. A self-adhering spacer is provided for maintaining accurate spacing between adjacent wooden boards or other construction members during construction activities. The spacer can be formed from a variety of materials, including wood, metal, or plastic. The self-adhering spacer can also be shaped in a variety of configurations, including a T or L shape.
