Note: Hopper Stiffeners are standard on 9' bulk bins that are 3,4,5 and 6 rings high.
When to add hopper stiffeners:
All bins offered without hopper stiffeners are for normal use with standard feeds.
3,4 ring bins which are to be filled with soybean meal, high fat feeds or
non-free flowing materials require hopper seam stiffeners.
