Installing a Roof Ring
Quantity and part numbers of roof ring kits vary with the location placement and with the size of each bin.
The following procedure will be similar for each kit.
What You Should Know
The roof ring and threaded stud may become dislocated from each other during high winds or when the
inside pressure of the bin is too great. If a threaded stud is dislocated, the entire roof ring will become dis-
jointed. To prevent this, drill holes through the roof ring and the threaded stud (after the rings have been
installed and expanded to the correct size) and insert a cotter pin or bolt through each hole. See
Figure 8-
4, page 128 .
