Fellows: PLEASE!!! PLEASE!!! PLEASE!!! DO NOT USE CHAIN LINK
FENCE FOR TOWER WORK!!!!!!!!!!!!!!!!!
I would even be very suspicious of chain link fence toprail! I have seen some
of the stuff that is not tubing at all--just a piece of flat stock that is
into a cylinder and then galavanized. This sticks it together and makes it
appear to be a welded pipe but there is no welding. Under even a modest
load the NON-seam will just pop open. Not all of the stuff is made this
way but unless you know what you have I wouldn't use it!
