It would be very convenient if I could extend and
assemble my aluminum extension ladder (in place)
to a telescoping third leg for use as an 'agricultural'
ladder.

Have you investigated these articulated ladders that can fold and latch
in at least three places in the legs? I don't know the name or brand,
but the guy who installed our latest over-the-air internet antenna used
one and it looked pretty strong.

The top of the ladder wants to be about 12' in the air.
I suspect that would require an articulated ladder
specified in the 28' region. Nearest I can find is this
26' unit. It is really nice but far more than I want to
pay for a 'single use' tool:

I guess what I would like to see is an adapter that bolts
on to the top rung of my extension ladder using a yoke
that adapts a piece of 2" conduit as a third leg.
Perhaps aircraft cables from the bottom of the leg
to the legs of the ladder for stability.

I could lean the (nearly) retracted ladder against
a ceiling joist, climb it and fix the 3rd leg adapter
over the top of the joist, clip the cables to the
bottom of the ladder, then extend the ladder to
working height.


Rent one.
