>From the Preformed Line Products Big Grip application procedure:
http://www.preformed.com/artsfest/files/AppProc/SP2049-3.pdf
"After original installation, Big-Grip dead-ends may be
removed and reapplied two times, if necessary, for the
purpose of retensioning guys. If removal is necessary
after a Big-Grip dead-end has been installed for a
period greater than 3 months, it should be replaced
with a new one."
