1. To connect wind ring pipe to the stiffeners, attach with 3/8" x 1" bolts through the flange of the
stiffener. In some cases field drilling of wind ring locations may be required. (See Figure 14A.)
2. Attach wind ring pipe section to stiffener using two (2) 3/8" x 6" (SS-7248) wind ring clamps.
3. Place pipes end to end without overlapping. Fasten together using two (2) wind ring couplers and
six (6) 3/8" x 1" flanged head bolts with flanged nuts. Couplers should be centered on the seam
of pipes.
Wind rings must be installed in relation to the ladder rungs as shown here, to ensure
