ABSTRACT:
A stabilizer jig for holding a distance measuring laser for determining distances measured along an angle. When an escalator is being installed in a construction site, the jig may be used to make difficult distance measurements between floors to ascertain that the construction distances are correct for the manufactured escalator system. A rotating pocket holds the laser and measures the angle while holding the laser steady as it makes the distance determination.
