Abstract: An adjustable installation device for hanging objects on vertical structures is described. In one example, an adjustable installation device includes a body section having a first track member slidably positioned within a second track member, a foot section coupled to the second track member, and a head section rotatably coupled to the first track member at a pivot point. The head section is at least partly rotatable about the pivot point and includes plates extending from an end of the head section, guide holes formed through the plates on a common centerline that extends through a center of each of the guide holes, and an alignment device operable to align the common centerline with a defined plane. The first and second track members are collectively operable to slide the foot and head sections in opposite linear directions to adjust a distance between the foot section and the common centerline.
