Our tallest new 3 story tool is lightweight and easy to use to get to 3 story homes, businesses, churches, schools, etc. and also for 2 story homes etc.
It can be used for 1 story homes, etc. but you would have to separate the tool in half and carry 2 pieces with one or two hands.  It's not practical for this reason.  That's why we have added a 1 Story tool to help in this matter.
