Years ago they made two models. The TRZ-80 and TRX-80. I got the TRX-80
for 72 foot and lesser towers. I assume the TRX-80HD is for 72 foot and
below towers and the TRX100HD is for the 89 foot and taller towers.
The one I have I have used with mine in 4 locations and I helped raise a
newer 72 footer 5 years ago. The main parts to consider are the winch (the
original fell apart 5 years after I bought it). I now use the K-1550 and
replaced the cable with some 3/8". Make sure the cable is long enough to
lay the tower all the way down leaving several turns on the winch.
Hope this helps.
