US Patent 7810250 Method and apparatus to mark opposing surfaces

The technology of the present application provides a system and method for marking opposing surfaces of varying sizes, shapes, and materials. This system and method allow a user to transfer the outline or location of a relevant feature such as, for example, a fastener, utility outlet, architectural feature, or window or door, from one surface to another through the use of a transferable marking substance, thereby eliminating the need for complicated and limited fixtures or time consuming and often inaccurate manual measurements.
