At the center of the marking device there may be a central hole, and attached to the backplate, are two extendable arms, each designed with a pin attachment to make marks and/or small holes in the wall material. The extendable arms are attached to the backplate in a manner that the arm pin attachments on each arm are perfectly aligned with the central hole. Using a set of gears or other method, the extendable arms are fitted to the back plate in a manner whereby the extension and/or retraction of one arm causes the other arm to move in an equal, but opposite manner. With this, the holes and/or marks will be equidistant from the central hole/pin hole, and also in-line with the center hole/pin hole and each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for making collinear equidistant marks","description":"The present invention is directed to a marking device that includes a main backplate.
