The current Phillystran (PS) jacket is bonded to the Kevlar core. The
core is twisted strands, much like 7x19 wire rope and I think that adds
to the grip of the jacket to the Kevlar. The jacket is only thick
enough to protect the Kevlar from UV. I measured the jacket on 3
different breaking strength (1200, 2100, 6700#) current Phillys and they
were all the same thickness +/- the accuracy of measurement with a
digital caliper and how well the Kevlar was centered in the jacket. The
jacket is the same thickness as on my 26,000# Philly of many years of
age and the non-adhering jacket.
I haven't tested grips for PS yet on my tension tester, but I have no
reason to doubt they work as well as grips on EHS. I used them on my
boom and element guys with the HPTG-2100-I.
Check the installation instructions for the PS as it specifies a
pretension value and then re-tension after 24 hours to remove the
initial set.

Question..I have a tower to put up for a ham in the Atl area.. He is using
PhillyStrand for the top set of guys,, and steel 1X7 EHS below that.. He
ordered it from the most famous place,, and they sent guy grips,,, what we
call performs for the phillystrand..Has any of you done this before ?? I
have never used them on Philly. Seems to me that philly is too soft and
pliable not to allow gripping strength. A steel cable is not giving and the
grip has positive gripping. So,, what has anyone done along this idea. I
want to know that the top set of philly is not going anywhere while I am on
this tower...73 Dan N4GNR
