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. Prevent this by staking the expansion bolt threads at the jam nut location (after the rings have
been installed and expanded to the correct size), use of suitable thread locking compounds or other effec-
tive methods. See
1. Determine the quantity of roof ring clips (C) needed for the roof ring section (B) being installed.
NOTE:
Each roof panel rib must have a roof ring clip installed.
2. Install a flange bolt (A) to the roof ring clip (C), and install a sealing washer (E) to the underside of
the roof ring clip (C).
3. Slide each assembled roof ring clip (C) onto a roof ring section (B), and position each roof ring clip
(C) over each roof panel rib.
4. Install a flange nut (D) to each roof ring clip (C).
NOTE:
Do not tighten hardware until all roof ring sections have been installed.
