The best way to climb this tower is 'on the nose'. That is, you grab the
leg with your hands and put your feet on the downwards sloping diagonals and
start on up. The diagonals perfectly perfectly spaced steps. This is the same
way you climb AB-105 or similar towers that have all diagonals.

Hmm, too much torque, perhaps? Some of the little ones are easy to snap
but that just means you're tightening them too much. I don't remember what
the torque specs are but I'll try to find out and let you know.

It comes either completely disassembled or with the sections assembled.
The price is the same and either way it comes on an 8-foot pallet. In both
cases you and the truck driver can unload a tower in about 15 minutes.

Another method I would use before using a ginpole is to assemble it
one-piece-at-a-time, erector set style. It takes 2 guys on the tower but you
can do a 56-footer in a day and you don't have to assemble the sections on
the ground.

These Trylon Titan towers are one of the best bargains in ham radio -
96-feet for less than $2000.00. A 100-foot self-supporter from Rohn,
(SSV/RTP) will run about $5500.00.
My $1.98 worth.
