发明名称 POSITION MARKING DEVICE FOR SLOT HANGERS
摘要 A method of hanging an object on a wall with a marking device having a threaded shaft, an enlarged diameter head fixed at one end of the shaft, a pointed marking end fixed at an opposite end of the shaft, and a threaded nut mounted on the shaft for axial movement. The shaft of the marking device is positionable into the slot of the item to be hung, and is fixed therein by the nut. Upon positioning of the object and the marking device fixed thereto into desired mounted position on the wall, application of an axial force to the shaft of the marking device will cause a pointed end thereof to create a mark for insulation of a nail or other fastener in the wall at the point of the mark.
