> That's it. Many years ago I installed a Glenn Martin 70' aluminum tower
which used 4000I philly and used cable clamps.
That was probably in the days before the Big Grips were available.
Using cable clamps on the Phillystran led to cold-flow of the aramid fibers
and a reduction in strength - a big problem. But you weren't tensioning them
to the 400# you'd need for regular guys so your risk exposure was pretty
