If I may add my two cents. I used all Big Grips on my recent tower, on
both the Polygon FRP and EHS parts of the guys. They are really sweet
(to use a popular term). They're real easy to install and make a very
clean installation. They're also maintenance free. A question: "What
do you have to do annually to wire rope clamps?" The answer is check
them for tightness. And I'd bet that most hams don't do that,
especially those in the middle of the guy. Also clamps will eventually
need replacing. The Big Grip joint is as strong or stronger than the
material it is holding. Finally someone said that they were not cheap.
IMHO, wrong they are cheap. Add up what it would cost for three all
galvanized cable clamps plus add in a little amortized labor cost for
your annual inspection, and they are really cheap. I highly recommend
them; once you've used them, you'll never use clamps again. I guarantee
that. Purchase from Preformed needs to be in case lots of 25 each but
one can buy them individually from Texas Towers. You do need to buy the
type for your exact application, wire type and diameter.
Again, a very clean installation. Phil KB9CRY
