     Guy wire grips by Preformed Line Products are excellent guy wire
terminations and are fully rated for their appropriate wire rope application.
 Yes, they're strong enough.

    Are the 'different' grips with no grit new or used?  As far as I know,
all PLP grips use the grit on the bearing surfaces.  The same grips that
don't have the grit for one reason or another only have 60% of their gripping
power so the grit is necessary.  That's why they limit you to two removals
(install - remove - install - remove - install).

     Preformed grips can be put over paint or many other thin coatings that
may be on the guywire.

     No, grips are VERY specific for wire size, strands, lay and a bunch of
other factors.

    Probably.  The easiest thing to do is to measure the size of the guy wire
to determine its size and then use the corresponding grip, insuring that it
has the right COLOR marks on it for that size; i.e. 5/16 is black and 1/4 is

    Yes, there is a spec for thimble size for each grip size; i.e. 5/16 inch
grips use 1/2 inch thimbles and 1/4 inch grips use 1/2 inch thimbles.  The
factory also recommends heavy duty thimbles.

     You don't have to do anything special.  "For appearance and safety, the
strand tail should be cut as close as convenient to the crossover mark.  If
desired, the strand tail can, instead, extend through the loop for grounding

     BTW there are two crossover marks.  The first one (closest to the loop)
is for normal wire attachment. The second one is for when you're using
