According to the Phillystran instruction sheet, the comment below on the use of
the tie wrap is
incorrect. The tie wrap is used around the grip at the rod end - "Secure black
tie wrap around the
grip at the rod ends to secure ends. Tie wrap should be positioned to within
one (1) inch of the
rod ends of short leg". You can see this at
www.burghardt-amateur.com/Burghart/Phillystran/phillystran.html or on the sheet
supplied with the
cable and wraps.
I am not sure where I got it (instruction sheet from Texas Towers?), but I fill
the black cable end
caps with caulk and install.
A further note, the thimbles used are "oversized". For example, 1/2" thimbles
are used with 6700
and 11,000 lb cable.
The instructions also warn against wrapping only one leg completely. Rather,
you need to start the
wrap with the short end and very soon in the process start wrapping the long
end. This back and
forth continues to the end. I have found that using a fixed connection point
for the thimble and
the grip is essential, as has been discussed. Also, I wrap with the right hand
and tension with the
left for one end and then alternate hands for the other end. The wrapping of
the long end can be a
real pain if you wrap as if it were EHS. I find that when wrapping the long
end that I need to pull
it further from the cable than I do with EHS. The instruction sheet also says
you can separate some
of the strands, and perhaps this would make the job simpler. I have never
tried that, since my way
works if sufficient attention is paid. If done correctly, the ends lay over
very nicely.

Hello Mike
When I bought my Philly guys and grips from Texas Towers Gerald showed me
how to install them, (Texas Towers is only about an hour drive from my QTH).
You start by laying the Philly in one side of the grip all the way down then
start the other side a few turns so that the grip has a hold on the Philly.
At this point put some tension on the Philly ( I used a clevis bolt around
the tower rung and though the the thimble on the big grip then stretched it
to the ground and stood on the philly). Continue to wrap the free leg around
the the grip and when you get to the end instead of using a screwdriver to
lock the last wrap use a pair of pliers to get it to lock in. It will look
just like the finish grip on the ehs nice and tight. The trick is to keep
the Philly taunt while you are wrapping the grip on.
The ty wraps are to hold the little black end caps on the ends of the
Philly.

I have several grips to install on (the newer style)
6700# Phillystran. I have no instructions for these
grips, per se, (I've asked TexasTowers for them -
didn't realize that I was not sent them) but do have
them for the "normal" grips for EHS. I have installed
several dozen of the EHS grips on 1/4" cable with
little difficulty. The final twist of the grip yields
a confidence-inspiring "snap" when done correctly.
With the Philly grips, however, I get no such snap. I
am following PLP's sheet that instructs one to split
the end of the grips and weave them back and forth
somewhat (rather than stitching one side fully then
the other). However, the tips of the grip tend to
bunch up since (it seems to me that) the jacket on the
Philly flows a bit. This leaves the end of the grip
quite easy to unwind - WAY more easily than the grips
on EHS (which require a screwdriver or other suitable
tool to get them started to unwind).
TT sent me tiewraps as well - never used any on EHS
grips so not sure what they are for...I hope these are
not expected to hold the end of the grips together...
Any ideas?
