Extension ladders are ideal for tradespeople working on the outside of buildings at height. They're constructed from two or more sections which slide apart and are then locked in place at maximum extension. This makes it easy to transport and store, as when fully collapsed it takes up considerably less space. Compact and lightweight, telescopic ladders are a particularly useful option for quick tasks and when space is tight. They're comprised of many more sections that slide inside, rather than over, each other.
