Patents are renewable if I recall. I don't know if they changed when

have lost touch with the IP law stuff.

Too bad they changed the patent laws as I've been using the tower clamo for nearly 30 years and figured any one who wanted to builfd one could. Actually a patent doesn't prevent you from building one for your self to use.

Patents are only good for 18 years.  Surely this thing is out by now.

Is it patented? Or require some unusual fabrication?

Apparently it's patented: http://www.superiormusic.com/towerjack.htm

*NOTICE !! /Tower Jack/ Products are patented under several United
States patents.
Manufacturing and selling of these products by anyone other than
Tower Jack Products of Mt. Juliet, TN is _strictly illegal_.*

I actually found a larger 'entire' picture on fleabay:
http://www.ebay.com/itm/Rohn-type-tower-install-removal-tool-leg-alignment-jack-heavy-duty-radio-ham-/271216494401


From the pictures I've seen, it seems that almost any metal
fabrication shop could crank them out. Maybe not for the same price,
but it sure doesn't look like it would be hard to make them.

One would guess that if your intention is not to sell them, you could
'one-off' a copy.
