This is a 25ft (8m) ladder with hooks for escaping from a window or balcony. Iron Hooks fit perfectly to most window frames in the world (see dimensions in pictures). Along with all the benefits, this ladder is easy to use. Even kids can climb it. It is difficult to use it if the ladder does not fit snugly against the wall but hangs in the air. This applies to any stairs, not only ours. In this case, you need to go down the side of the stairs as acrobats do in a circus (there is an image in the pictures).
