NOTE: Do not tighten the nuts (C) until all hardware has been installed attaching the inside stiffener (CTS–
2069XX) to the sidewall and the outside stiffener. Bins with an odd number of rings will use the
one-ring outside stiffener (CTS-2071XX), and bins with an even number of rings will use the two-
ring outside stiffener (CTS-2111XX or CTS-2116XX).
1. From the inside perimeter of the sidewall, place the bolt (B) through the hole located approximately 4
in. down from the top of the sidewall sheet (A).
NOTE: Install the bolts from the inside to the outside of the bin, passing through the inside stiffener,
corrugation spacer, sealing washer, sidewall sheet, and outside stiffener and flange nut.
2. On the inside perimeter, install a sealing washer (F), corrugation spacer (E), and inside stiffener (D).
3. Install a flange nut (C) to the bolt (B) and repeat this process with the remaining hardware. Tighten
hardware to the recommended torque specifications, see Bolt Torque Specifications, page 25 .
