The beauty of telescoping ladders is that they can be extended to different heights. However, this is limited by the distance upon which its individual rung can be adjusted. For example, if each rung can only be adjusted in increments of 1 foot, then you cannot expect to extend the telescoping ladder to 6.5 feet. You can, however, extend it to 7 feet or maybe even 6 feet. As long as the height you’re aiming for is less than the intended maximum height of the ladder, then you should be able to use this system.
