No, not crankups or sky needles, says it comes in 10 foot sections with
joining sleeves that hold the sections together while sections are being
bolted, gives a full 10 foot length. I'll scan the paper and you can see
the whole writeup. These are for stacking and guying. I assumed from the
model number it was a competitive tower to the Rohn 25, just didn't know
what Triexium material was. Re this ad I suspect the Triexium was only for
the guyed tower items.

Model TM-Series
The Sky Needle series supports large amateur beams.
Hinged base mount included for concrete base.
Geared tele-scopic winch included.
Motor included with 70', 90' & 100' models.
Come to Tri-Ex for innovative tower design and
engineering! Our towers are famous all over the
world for their strength, stress and wind resistance.
Now you can buy a superior Tri-Ex tower at
FACTORY SAVINGS!
Choose your metal. Towers can be fabricated in
steel to ASTM Specifications with hot-dipped gal-
vanized finish (done after construction so that inside
surfaces are zinc-coated, too). Or in Triexium™, our
lightweight, corrosion resisting, high-strength light
alloy.
Tri-Ex HAM towers are available self-supporting or
guyed; take your choice. The W series of crank-up
towers, the LM series of crank-up/tilt-over towers
and the TM sky needles are self-supporting.
Use your charge power to buy your tower. Tri-Ex
honors Visa and Master Charge credit cards. If you
have questions about tower accessories or which
size tower is right for your antenna, call Bill Salerno,
his technical sales know-how is ready to serve you.

That works great, if you're somewhere it's legal or permitted to drive
things into the ground. There's lots of field day sites around where
they're fine with you going there, but not fine with you driving things
into the ground, or making alterations in the site (like a big parking
lot). That's where various ballast and weight schemes are nice.
