The clamps used in the 1200 are the  3/16 and the end caps are required to keep 
the water out of the kevlar, water damage the kevlar 


I have several hundreds of feets of that and several dozens of  terminal kits 
and no failure,  maybe you overtightened the clamps

Subject: [TowerTalk] Phillystran Questions

  I had never used Phillystran before, but am currently using the light 
duty grade (1200 lb. tensile) for stabilizing a long aluminum tubing 
stinger atop an aluminum tower.

Based on recommendations from the supplier and info from this forum, I 
used 1/8" (or 3/16"?)  cable clamps to secure the ends of the 
Phillystran.  They had been in place for about a month when I undid one 
set to make some adjustments to the guy.  I noticed that the clamps had 
compressed or made deep cuts in the the Phillystran so that it appeared 
that its strength was probably compromised.  When I reclamped the 
adjusted cable, I didn't tighten the clamps to  the same degree as I had 
originally because of my concern for cutting into the cable.  I'm 
wondering whether these cuts are normal and don't seriously reduce the 
strength of the installation or not?  Should I have used a torque wrench 
or similar to tighten the clamps?

Also, end caps were supplied for the cable.  Are these merely decorative 
or do they serve some other function?

I'd appreciate any info that the forum can provide.
