I have a very awkward project location above the ceiling

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.

I can't help your issue, but this is a standard orchard ladder. I have
six of them in three different heights. I guess three leg ladders are
too expensive for the public, you don't see them in the big box
stores. But they are WAY better on uneven ground and far more
portable.

They're also much better at encroaching into a tree's canopy. I
borrowed one from my girlfriend when picking my apples, back when I
had both.
