Currently the Step Distance on Ladders is approx 12 inches ( 31 cms) This causes extra reach descending and leads to unbalancing especially with older less flexible persons. The Step Distance needs to be no greater than 7 Inches ( 18cms)
Ladder Manufacturers should give my idea a go. With just a little promotion I am sure Sales will be huge. I have experienced this Gap between the steps and my retired Carpenter husband is most precarious when using our current ladder. I would happily volunteer for testing should any manufacturer give this idea a go as it is a safety measure not only for the older person but the young as well.
