Among other things, ladders are rated by the weight they can safely hold.
The following copied from a web page.
a.. Type III, Light Duty / Household Use (200 pound load capacity): The
lightest rating, intended for short ladders that will be used very
infrequently and for very light-duty work.
b.. Type II, Medium Duty, Commercial Use (225 pound load capacity): For
light duty use around the house -- painting, cleaning, light repairs.
c.. Type I, Heavy Duty, Industrial Use (250 pound load capacity): Good all
around rating for household or commercial use. Sturdy enough for just about
any use.
d.. Type IA, Extra Heavy Duty/Professional Use (300 pound load capacity):
The highest rating. Very sturdy, and designed for rugged use in any capacity
on commercial or industrial sites.
Remember that the more highly rate a ladder is the more it weighs and the
more it costs
I used to have 24 foot one (that's two 12 foot sections that overlap and
give you about 20 feet full extended.
When it is extended quite a bit, there is a minimum amount of overlap which
makes it a whole lot more flexible. It can be a real thrill standing 12 feet
of the ground on a bouncing ladder.

Two other considerations.
You can use the as two 20 footers and get stands to support a plank to act
as a scaffold.
Do you really need a ladder that big?

Try it out first. Check for a rating sticker. See how heavy it is. See how
well the sections slide together. See how well the sections lock together.

It's your neck that you will put in jeopardy. Know what you are getting
into.

When I moved from a two story house to a single story seven years ago, I
sold my old ladder for $50

I think things are worth what someone is willing to pay for them. Many

a
28 foot fiberglass ladder that cost me close to $400 when I bought it.
Next
year when I get a new one, I'm hoping I don't have to pay to get rid of
it.

Gents;

My neighbor has an old 40 foot aluminum extension ladder that he has
stored for a number of years in his garage. He has offered to sell it
to me if I want it. My question is this: Assuming I have to replace
the ropes, what would a fair price be for a used ladder of this size?

Thanks
