Attachments should be engineered and sized appropriately to resist the
applied loads.
INSTALLATION CONSIDERATIONS
The Manufacturer's instructions regarding bolt tightening should be
followed for all attachment connections. The Purchaser should be aware
that over-tightening of the bolts may lead to ovalization of the pole cross
section, which can possibly initiate longitudinal cracking along the pole
length.
