Recently I posted the following question.

> I've installed the bracket per the drawing, but it doesn't seem right...
> it's just floating on the tower, resting on the cross braces.  All of the

> through the cross braces.  Is this right?

I got many replies, some of which suggested this is correct, and others
(usually using older guy bracket configurations with torque bars) did find
they clamped tightly on the tower legs.  I received a definitive answer from
Rohn:

So, following the LXC prime directive, I will leave it as it is.  Also, note
that when the bracket is installed correctly, the part number stamped on the
guy bracket (GB55D) is upside down.

1 more set of guys to build, two C31XRs to assemble and a 40-2CD to rebuild
and up it goes...
