ABSTRACT:
The tool of this invention comprises a collar which may be attached to a pivot rod extending from the underside of the upper pivot assembly of a swinging or revolving door, the collar having a recess in the top surface of the collar for receiving the upper pivot rod, said recess being dimensioned to snugly fit the pivot rod without substantial lateral movement of the collar, so as to align the central vertical axes of the collar and upper pivot rod, the bottom of the recess having a central aperture, a means for rigidly but removably attaching the collar to the pivot rod, and means associated with the collar for generating a marker in vertical alignment with the central aperture in the bottom of the recess to thereby designate the center point of the bottom pivot.
