Install the upper rollers as shown in (FIG. 4). Note the 1”NC jamb nut is placed in between the two ½” thick steel plates
of the guide frame. Thread the jamb nut onto the 1”x7” bolt until it has reached the end of the threads. Thread the
1”NC lock nut onto the bolt and tighten so that the jamb nut and lock nut are tight and rigid against the outside ½” steel
guide frame plate. Note the upper roller should have approximately 1/4” movement along the bolt shaft when tight.
