     Cable clamps are the buggy whips of the guy wire industry.  Just about
everyone (tower erectors, power companies, utilities, TV cable companies,
etc.) have converted to preforms (or other devices) instead of clamps.

     You ever try to bend EHS while installing cable clamps?  What a pain.
 Also, the clamps will loosen up the first time they go through a temperature
cycle.  You did re-tighten everything before you put it up didn't you?

     You can un-wrap Preforms twice.  A maximum use is
install-remove-install-remove-install.  The reason has to do with the grit
inside the grip that may be loosend and lost during the install-remove cycle,
thus losing some of its gripping strength.
