Step Assembly
17) The ends of the steps are bolted to the step body with 5/16" slot truss bolts and flange nuts. The ends are
bolted under and behind the step body. Tighten all 8 bolts after they are all in place and assemble all of the
steps.
NOTE: Some of these bolts will need to be removed for attaching the step to the horizontal bracket. The front
inside bolt may need to be removed if it interferes with the horizontal bracket or the step under it.
Step Attachment
18) The step attaches to the horizontal bracket with two top bolts in the back of the step assembly. Loosen the
nuts from the bolts and hang the step in place and refasten the nuts.
Hang a step on the next horizontal bracket located at the bottom of the bottom ring. The step between the two
brackets should be put in place.
