This telescopic ladder can easily be transported and stored, and yet is strong and robust enough for professional and trade use. Simple and easy to use - the ladder is extended one rung at a time, from the base upwards, with the locking mechanism on each rung clicking into place. To close the ladder the triggers are squeezed together and the Laddermatic™ retracts easily and smoothly with no risk of trapped fingers due to its unique safety features. The ladder can be extended to any length up to its maximum size and with a 12' maximum length this ladder can be used to reach the highest of ceilings.
