40 Series Roof Ring Installation

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
disjointed. 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 2 on Page 2.)

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. (See Figure 1.)

40 Series Roof Ring Installation

5. Locate a threaded stud (F) and install stud nuts (G) evenly and to the center of the threaded stud (F).

6. Install the threaded stud (F) with stud nuts (G) to the end of the roof ring section (B).

NOTE: Install the threaded stud (F) to the side where the next roof ring section will be installed.

7. Repeat this process, installing each new roof ring section end onto the preceding threaded stud
just installed.

8. When all roof ring sections are installed, tighten each roof ring clip (B) to the recommended torque
specifications. See bolt torque specifications.

9. Adjust each stud nut (G) outward, expanding each roof ring section. Continue this procedure evenly
until the roof ring raises the roof, showing a slight crown. (See Figure 2.)
