Abstract
A device for marking the location of a hanger for an item to be hung. An elongated element is provided for receiving an item to be hung. The element has a plunger received thereon with a marker associated with the plunger. Depression of the plunger moves the marker from a non-marking position to a marking position which is opposite the point of support of the item whereby with the item located on the elongated element and held adjacent the wall where the item is to be hung, depression of the plunger will move the marker into contact with the wall to mark the point where a hanger should be installed to later support the item at the same location on the wall where it was held.
