Extension ladders are ladders whose length can be extended for reaching higher areas. Generally, they can increase up to almost double their height. In an extension ladder, two ladders of the same size are combined, and then one is slid up to increase the height. Since some portions of the ladder overlap, the actual height is not truly double but a few feet less than double. Thus, whatever the height you want to reach, the length of the extension ladder should be a few feet more than the point you want to access. Some extension ladders come in a combination of three ladders.

Extension ladders are mostly used for outside jobs that require reaching extended heights. Small size extension ladders can slide out by pulling with your hands. Larger ladders come with rope loops to help them extend to their maximum height. Once opened, it is very essential to secure these ladders properly. For this purpose, stay locks can either be secured with hands or tools to tighten them. It should also be ensured that the ladder is resting properly on ground and is stable at the top.

Besides the standing model, extension ladders are also available in telescopic and foldable models. For accessing poles, some extension ladders are fitted with a pole chain at the top rung. For greater heights, extension ladders such as rope and pulley types are found suitable.
