Bin Stairs and Platform Assembly

Step to Horizontal Bar Attachment

Attach step assembly to the top horizontal bracket
with two 5/16” x 3/4” Truss head bolts. Use the outer
set of holes in the horizontal bracket. Attach another
step to the lower horizontal bracket. Maneuver the
next step in between the others and attach the top
side tabs to the outside of the upper steps with truss
head bolts see Figure 8. Attach lower step tabs in
the same manner.

Tie Strap Attachment

Attach the steps to each other with the tie straps (LDR-
4090). Use 5/16 x 3/4” truss head bolts and nuts to
attach the strap to the holes provided on the ends of
the step. Align the step slots and level the steps be-
fore tightening. The steps will align to curvature and
wall brackets. When all the parts of the top section
are in place tighten all the bolts.
