I have a very awkward project location above the ceiling

garage. I don't get to move the location.

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.

That way, I could climb over all the obstructions
without disturbing anything. Note that there is not
enough clearance to use a step ladder in this awful
location and there is no safe place to rest the top
of an extension ladder.

My Google-Fu has failed to uncover a good answer.
This is as close as I have come:

It looks promising but there is not enough information
for me to understand what this product does. I assume it
is only an accessory to their brand of ladder.

How would you solve this problem?

(I want to clean up the hole I cut in the ceiling.
It's the right size and works great but it is not
super nice looking. I have the fan mounted in
anticipation of rain and I really don't
want to take it apart to access from the roof.)

Do you have enough of a footprint directly under the spot to use one of
the small telescopic lifts? You could rent one for the weekend for less
than the copay for the ER visit...
