Used to reach up high!
One ladder is 3.40m long and can be easily slid into the second one, which in total reaches a height of 6.10m. It's an aluminium ladder, so despite its length the ladder is rather light.
Be careful, obviously! Some H&S advise:
Grab another person to hold the ladder and make sure the surface you place it on is level & solid. Ensure there is at least a four-rung overlap on each extension section and the top of the ladder extends at least on metre above its (equally solid & level) landing point.
