Thanks for pointing out the Trestle Ladder.
I had never seen one of those before.

I had known about the "Orchard" or "Tripod" ladders:

But, they only go up to about 12 feet.

It seems the Trestle ladder goes to 26 feet.

I haven't actually measured the distance, but, I've eyeballed it
to something around 20 to 25 feet or so (it's two tall ceilings
high).
