Chapter 3: Assembling Winding Bin Stair Sections
Assembling the Bottom Sidewall Attachment Bracket
The bottom sidewall attachment bracket will be used only in the bottom ring for installing the winding bin
stairs.
1. Using a square, attach the support channel (46) to the bottom of the sidewall sheet bracket (45) and
secure them using flange bolts (2) and flange nuts (3).
2. Attach the inside stringer support (48) and bin stair handrail post (49) to the support channel (46)
using flange bolts (2) and flange nuts (3).
NOTE:
If an inside handrail is needed, replace inside stringer support (48) with another bin stair
handrail post (49).
