Typically when raising a ladder, more than one individual is needed. One person has to stand at the bottom of the ladder to keep it from kicking out while raising or lowering it. When done by only one individual there is a risk of injury and not everyone has a second hand to help raise or lower a ladder all the time. There is also a risk of the ladder slipping out when working high on a ladder. This product is design to act as that second individual at the bottom of the ladder. This will help a single person raise and lower a ladder and feel confident that the ladder is secure on the ground when working high up on the ladder.
