[TowerTalk] How to clamp Phillystan HPTG 1200I guy cable?

[john at kk9a.com]

If I recall correctly there was a time between potted ends and Big Grips that wire rope clips were recommended for Phillystran.   I had a few guys like this on my Rohn 65G tower while in Chicago.  I still use wire rope clips for Phillystran boom trusses usually HTPG-2100I pr HTPG-4000I.  Yes it crushed the cable but I have yet to have an issue with the Kevlar fibers plus using a Big Grip would defeat must of the purpose for having a non-conductive truss.

Having been using Phyillystan for a couple of decades I would certainly NOT advise using any kind of compression clamps.

You would be crushing the Kevlar fibers which is where the strength is.  
The preforms are not only the manufacturers recommended but they are not that expensive to do it right and above all safe.  
Is it worth it to do it right.
