Abstract: The disclosure is directed to a wall marker for marking a desired location on a wall for a support arranged to mount an object. The wall marker generally comprises a suction cup means, a marking means mounted upon the suction cup means and arranged to extend within the confines of a central concave portion of the suction cup means and means associated with the suction cup means and the marking means to retain the marking means in a normally spaced relation from the wall upon which the suction cup means is adhered to. In accordance, an important feature of the invention, the marking means is selectively axially displaceable relative to the suction cup means whereby the marking means may be selectively displaced into contact with the wall to create a visible mark on the wall.
