Abstract: A measuring device hanger is engageable with one of the standard holes in a vehicle body, and suspends a conventional measuring device therefrom. A head is small enough to pass through the smallest of holes in a vehicle body; and, the head is expansible to lock within the largest of holes in a vehicle body. The head is in two parts, one part being on each of two jaws. The jaws are pivotal away from each other to separate the two parts of the head to lock the head within a hole. A body mounts a shaft fixed with respect to the body. The shaft carries a threaded stud which extends through a cam block. Thus, as the body and the shaft are rotated, the threaded stud rotates to move the cam block and urge the jaws away from each other. The body defines a hole that receives the standard measuring device, and a set screw secures the measuring device.
