[TowerTalk] Fw: Insulators

[David Robbins K1TTT]

Those are probably rated much less than power insulators since they are only
meant to be in series with (probably) hs type guy wire.  There are quite a
few manufacturers, if you search for their web sites you might be able to
match them up with a catalog... some of the common ones:
a.b. chance
Joslyn
Continental Electric Co
Stanley G. Flagg Co
And probably a few others, those just showed up on a quick google search.
