    I think that the reason is that the bottom-most shackle represents a 
convenient attachment point for your comealong-and-cablegrip to pull the guy 
wire enough for attachment - otherwise there isn't an anchor for the 

    You need to pull the guy wire enough to get the right length for 
attachment plus enough pull to get some initial tension (say 100# or so) and 
you need something for the comealong to pull against. 

    When I'm erecting a tower, use 3 comealongs and 3 Klein cablegrips to do 
the initial plumb-and-tension when connecting the guy wires. 

    In my case I just use a nylon sling attached below the anchor nut or eye 
for the attachment.
