Abstract
The invention relates to a parallel spacing guide that when attached to a hand-held marking device (spray gun), it enables the user to mark an accurate and consistent extended line one to four feet from a curb, wall, or other vertical surface; and one to four feet from a line or score mark along the ground in cases where a vertical surface is temporarily absent. This is achieved by having the parallel spacing guide soundly attached to a hand-held marking device. While holding the parallel spacing guide in one hand by the embodied handle and the attached marking device by it's handle in the other hand, the user pushes the invention along the street or highway with the end of the parallel spacing guide butted against the curb or wall while simultaneously using the marking device to mark the line by discharging paint or chalk.
