A Concertina is basically something that just folds out.
Concertina Ladders work in the same way, which is why they are becoming so popular today.
The worst thing about carrying a big ladder around is that they are difficult to maneuver, and get to where you want them.
When you need to go through a building this becomes even more challenging.
To make it easier, there are telescopic and concertina ladders which you simply pull out to set up.
These are brilliant technology, and are becoming more and more popular.
A lot of people use these to get into their lofts and attics, because they are relatively cheap, light and easy to use.
To set one up in your ladder, all you need to do is remove the man hole (which is done with a pole in most cases, and then hook the ladder and pull it down.
The Concertina Ladders act like multiple scissors connected together, and stretch out until the touch the ground.
From there, you can easily walk up them into the attic or loft.
Some fold out into a straight ladder from three or four pieces, but I much prefer the vertical concertina types.
You can purchase these ladders in steel, aluminum, plastic, fiberglass and timber.
They all have their own advantages, but the aluminum is light weight, strong and it looks good in a house.
You can also set these up very easily too, as a pose to the heavier wooden ones.
If you haven't looked into getting a concertina ladder, now is your time; they are great technology.
