US Patent 7503126 Wall-hanging-aid device and method of use

A wall-hanging-aid device comprises four retractable tape measures encased in a housing and at least one template for aligning a hanging position or hooking position of an object on a vertical surface, such as a picture on a wall. In one embodiment a first vertical tape measure extends from the bottom of the housing and includes a measurement scale and a lip for securing the tape to an item being measured. Opposite this vertical tape measure, a single aligning fin or template extends from the housing and includes a marking-hole guide for aligning the desired hooking position on the wall. The two other tape measures extend in opposite directions generally perpendicular to the vertical tape measure.
